Introduction
Introduction
Congratulations on choosing your Honda off-
road motorcycle.
When you own a Honda, you’re part of a
worldwide family of satisfied customers –
people who appreciate Honda’s reputation for
building quality into every product.
Your Honda was designed as a recreational
motorcycle for off-road use by one rider only.
It’s an ideal bike for younger, beginning riders.
Before riding, take time to get acquainted with
your motorcycle and how it works. To protect
your investment, we urge you to take
responsibility for keeping your motorcycle well
maintained. Scheduled service is a must, of
course. But it’s just as important to observe the
break-in guidelines, and perform all the pre-
ride and other periodic checks detailed in this
manual.
We also recommend that you read the owner’s
manual before you ride. It’s full of facts,
instructions, safety information, and helpful
tips. To make it easy to use, the manual
contains a detailed list of topics at the
beginning of each section and an index at the
back of the book.
As you read this manual, you will find
information that is preceded by a
symbol. This information is intended to help
you avoid damage to your Honda, other
property, or the environment.
Read the Warranties Booklet (page 164)
thoroughly so you understand the coverages
that protect your new Honda and are aware of
your rights and responsibilities.

Important Safety Information
Your motorcycle can provide many years of
service and pleasure–if you take responsibility
for your own safety and understand the
challenges you can meet while riding.
This motorcycle has been designed for younger
riders. However, not all youngsters are
physically or emotionally ready to ride.
Therefore, before parents allow any youngster
to ride this motorcycle, we urge them to
carefully read the Important Message to
Parents beginning on page 5 and the Parents,
Youngsters and Off -Highway Motorcycles
booklet that came with the motorcycle (USA
only).
There is much that you can do to protect
yourself when you ride. You’ll find many
helpful recommendations throughout this
manual. The following are a few that we
consider to be most important.
Always Wear a Helmet
It’s a proven fact: helmets significantly reduce
the number and severity of head injuries. So
always wear an approved motorcycle helmet.
We also recommend that you wear eye
protection, sturdy boots, gloves, and other
protective gear (page 24).
Never Carry a Passenger
Your motorcycle is designed for one person
only. There are no handholds, footrests, or seat
for a second person–so never carry a passenger.
A passenger could interfere with your ability to
move around to maintain your balance and
control of the motorcycle.

Important Safety Information
Ride Off-road Only
Your motorcycle is designed and manufactured for
off-road use only. The tires are not made for
pavement, and the motorcycle does not have turn
signals and other features required for use on public
roads. If you need to cross a paved or public road,
get off and walk your motorcycle across.
Take Time to Learn and Practice
Developing off-road riding skills is a gradual,
step-by-step process. Start by practicing at low
speeds in a safe area and slowly build your
skills. Personal instruction from an experienced
rider can also be valuable.
If you need assistance, ask your dealer about
riding groups in your area.
Also be sure to read the Tips & Practice Guide
for the Off -Highway Motorcyclist booklet that
came with your motorcycle (USA only).
Be Alert for Off-road Hazards
The terrain can present a variety of challenges
when you ride off-road. Continually ‘‘read’’ the
terrain for unexpected turns, drop-offs, rocks,
ruts, and other hazards. Always keep your
speed low enough to allow time to see and react
to hazards.
Ride within Your Limits
Pushing limits is another major cause of
motorcycle crashes. Never ride beyond your
personal abilities or faster than conditions
warrant. Remember that alcohol, drugs, fatigue,
and inattention can significantly reduce your
ability to make good judgments and ride safely.
20YM CRF125FFB_31K28B60_FM.book 3 ページ ２０１９年３月１日 金曜日 午後１時４８分

Important Safety Information
Don’t Drink and Ride
Alcohol and riding don’t mix. Even one drink
can reduce your ability to respond to changing
conditions, and your reaction time gets worse
with every additional drink. So don’t drink and
ride, and don’t let your friends drink and ride
either.
Keep Your Honda in Safe Condition
It’s important to keep your motorcycle properly
maintained and in safe riding condition.
Having a breakdown can be difficult, especially
if you are stranded off-road far from your base.
To help avoid problems, inspect your
motorcycle before every ride and perform all
recommended maintenance.

Important Message to Parents
Your child’s safety is very important to Honda.
That’s why we urge you to read this message
before you let any young person ride this
motorcycle. Off-road riding can be fun. But, as
with riding a bicycle, bad judgment can result
in injury, and we don’t want that to happen! As
a parent, you can help prevent accidents by
making good decisions about if, when, and how
your youngster rides this motorcycle.
The first decision you’ll need to make is
whether your youngster is ready to ride. Riding
readiness varies widely from one person to
another, and age and size are not the only
factors.
PHYSICAL ABILITY is an important
consideration. For example, riders must be big
enough to hold the motorcycle up, get on, and
comfortably sit on the seat with both feet
touching the ground. They should also be able
to easily reach and work the brakes, throttle,
and all other controls.
ATHLETIC ABILITY is necessary for riding a
motorcycle. Generally speaking, your
youngster should be good at riding a bicycle
before getting on a motorcycle. Can your
youngster judge speeds and distances while
riding a bicycle and react with proper hand and
foot actions? Anyone who does not have good
coordination, balance, and agility is not ready
to ride this motorcycle.
Riding Readiness

Important Message to Parents
MENTAL AND EMOTIONAL MATURITY
are requirements for safe riding. Does your
youngster think through problems and come to
logical solutions? On a bicycle, does your
youngster obey safe riding rules? Be honest!
Young people who take unnecessary risks,
make bad judgments, and don’t obey rules are
not ready to ride this motorcycle.
If you decide that your youngster is ready to
safely operate this motorcycle, make sure both
of you carefully read and understand the
owner’s manual before riding. Also be sure that
your youngster has a helmet and other
appropriate riding equipment, and always
wears it when operating the vehicle or sitting
on it.
GOOD INSTRUCTION is an important part of
hands-on training. The teacher can either be
you or another responsible adult who has
experience with off-road motorcycle riding.
(For help in finding a qualified instructor, talk
with your dealer.) Even if you’re not the main
teacher, it’s up to you to ensure your
youngster’s safety. Remember, learning to ride
a motorcycle is a gradual, step-by-step process.
It takes time, patience, and practice–many
hours over a period of weeks or months.
Instruction and Supervision

Important Message to Parents
SUPERVISION is another important obligation
of parents. Even after youngsters have become
skilled off-road riders, they should always ride
with adult supervision. It helps to regularly
remind young riders of basic safety rules and
precautions. And remember, it’s your
responsibility to see that the motorcycle is
properly maintained and kept in safe operating
condition.
SAFE AND RESPONSIBLE RIDING must be
an on-going commitment – by you and your
youngster. When you both put safety first, you
can enjoy more peace of mind, and your
youngster can enjoy more hours of safe off-
road riding.
For your convenience, this CRF125F/FB
comes with an ignition switch and key. Remove
the key when the motorcycle is parked to help
prevent unauthorized use.

Loading, Accessories & Modifications
Your Honda was designed as a rider-only
motorcycle. It was not designed to carry a
passenger or cargo. A passenger or cargo could
interfere with your ability to move around to
maintain your balance and control of the
motorcycle.
In addition, exceeding the weight limits or
carrying an unbalanced load can seriously
affect your motorcycle’s handling, braking, and
stability. Adding accessories or making
modifications that change this motorcycle’s
design and performance can also make it
unsafe. Also, the weight of any accessories will
reduce the maximum load the motorcycle can
carry.
More specific information on load limits,
accessories, and modifications follows.
How much weight you put on your motorcycle,
and how you load it, are important to your safety.
If you decide to carry cargo, you should be aware
of the following information.
Loading
Overloading or carrying a passenger
can cause a crash and you can be
seriously hurt or killed.
Follow all load limits and other loading
guidelines in this manual.

Following are the load limits for your
motorcycle:
Maximum weight capacity
CRF125F: 176 lb (80 kg)
CRF125FB: 194 lb (88 kg)
Includes the weight of the rider and any
accessories.
Loading Guidelines
As discussed on page 8, we recommend that
you do not carry any cargo on this motorcycle.
However, if you decide to carry cargo, ride at
reduced speeds and follow these common-
sense guidelines:
• Keep cargo small and light. Make sure it
cannot easily be caught on brush or other
objects, and that it does not interfere with
your ability to shift position to maintain
balance and stability.
• Place weight as close to the center of the
motorcycle as possible.
• Do not attach large or heavy items (such as a
sleeping bag or tent) to the handlebar, fork,
or front fender.
• Make sure that all cargo is tied down
securely.
• Never exceed the maximum weight limit.
• Check that both tires are inflated properly
(page 98).

Loading, Accessories & Modifications
Modifying your motorcycle or using non-
Honda accessories can make your motorcycle
unsafe.
Before you consider making any modifications
or adding an accessory, be sure to read the
following information.
Accessories
We strongly recommend that you use only
Honda Genuine Accessories that have been
specifically designed or approved and tested for
your motorcycle. Because Honda cannot test all
other accessories, you must be personally
responsible for proper selection, installation,
and use of non-Honda accessories. Check with
your dealer for assistance and always follow
this guideline:
• Make sure the accessory does not reduce
ground clearance and lean angle, limit
suspension travel or steering travel, alter
your riding position, or interfere with
operating any controls.
Accessories & Modifications
Improper accessories or modifications
can cause a crash in which you can be
seriously hurt or killed.
Follow all instructions in this owner’s
manual regarding modifications and
accessories.

Modifications
We strongly advise you not to remove any
original equipment or modify your motorcycle
in any way that would change its design or
operation. Such changes could seriously impair
your motorcycle’s handling, stability, and
braking, making it unsafe to ride.
We also advise you not to make any
modifications or remove any equipment (such
as the USDA qualified spark arrester or
emission control system components) that
would make the motorcycle illegal in your area.

Before Riding
Are You Ready to Ride?
Before you ride your motorcycle for the first
time, we strongly recommend that you:
• read this owner’s manual
• make sure you understand all the safety
messages
• know how to operate all the controls
Before each ride, we also suggest that you
make sure you:
• are in good physical and mental condition
• are free of alcohol and drugs
• are wearing an approved motorcycle helmet
(with chin strap tightened securely), eye
protection, and other protective clothing
For your safety, we strongly recommend that
you always wear an approved motorcycle
helmet, eye protection, boots, gloves, long
pants, and a long-sleeved jersey, shirt, or jacket
whenever you ride. Although complete
protection is not possible, wearing the proper
gear can reduce the chance of injury when you
ride. Following are suggestions to help you
choose the proper gear.

Are You Ready to Ride?
Helmets and Eye Protection
Your helmet is your most important piece of
riding gear because it offers the best protection
against head injuries. A helmet should fit your
head comfortably and have a chin strap that can
be tightened securely.
An open-face helmet offers some protection,
but a full-face helmet offers more. Regardless
of the style, look for a DOT (Department of
Transportation) sticker on any helmet you buy
(USA only). Always wear a face shield or
goggles to protect your eyes and help your
vision.
Additional Riding Gear
In addition to a helmet and eye protection, we
also recommend:
• Sturdy off-road motorcycle boots to help
protect your feet, ankles, and lower legs.
• Off-road motorcycle gloves to help protect
your hands.
• Riding pants with knee and hip pads, a riding
jersey with padded elbows, and a chest/
shoulder protector.
Not wearing a helmet increases the
chance of serious injury or death in a
crash.
Be sure you always wear a helmet, eye
protection and other protective apparel
when you ride.

Before Riding
Is Your Motorcycle Ready to Ride?
Before each ride, it’s important to inspect your
motorcycle and make sure any problem you
find is corrected. A pre-ride inspection is a
must because off-road riding can be tough on a
motorcycle and you don’t want to have a
breakdown far from help.
Note to Parents:
If a youngster will be performing any of the
following pre-ride inspection procedures, it’s
your responsibility to provide careful
supervision and make sure they are performed
safely.
Check the following items before you get on
the motorcycle:
Improperly maintaining this motorcycle
or failing to correct a problem before
riding can cause a crash in which you
can be seriously hurt or killed.
Always perform a pre-ride inspection
before every ride and correct any
problems.
Pre-ride Inspection
Tires Use a gauge to check the air
pressure. Adjust if needed. Also
look for signs of damage or
excessive wear (page 98).
Spokes &
Rims
Make sure the spokes and the
rims lock are tight. Also check
the rims for damage (page 93).

Leaks Look under the motorcycle for
signs of leaking fluids (fuel,
engine oil, brake fluid).
Engine Oil Check the level and add oil if
needed (page 64).
Fuel Check the level and add fuel
(page 59) if needed. Also make
sure the fuel fill cap is securely
fastened.
Drive Chain Check the condition and slack.
Adjust and lubricate if needed.
Also check the chain slider for
wear and replace if needed
(page 103).

Basic Operation & Riding
Before riding your motorcycle for the first
time, please review the Important Safety
Information beginning on page 2 and the
previous section, titled Before Riding.
Even if you have ridden other motorcycles,
take time to become familiar with how this
motorcycle works and handles. Practice in a
safe area until you build up your skills and get
accustomed to your motorcycle’s size and
weight.
For your safety, avoid starting or operating the
engine in an enclosed area such as a garage.
Your motorcycle’s exhaust contains poisonous
carbon monoxide gas which can collect rapidly
in an enclosed area and cause illness or death.
Your motorcycle is not equipped with lights.
Do not ride at night.
Safe Riding Precautions
Running the engine of your vehicle
while in an enclosed or even partially
enclosed area can cause a rapid build-
up of toxic carbon monoxide gas.
Breathing this colorless, odorless gas
can quickly cause unconsciousness
and lead to death.

Shifting Gears
Your motorcycle has four forward gears.
To start riding, after the engine has been
warmed and the side stand raised:
1.Close the throttle and pull the front brake
lever in.
2.Pull the clutch lever all the way in.
3.Depress the shift lever from neutral down to
first gear.
4.Release the front brake. Gradually open the
throttle while you slowly release the clutch
lever.
If engine rpm (speed) is too low when you
release the clutch lever, the engine will stall.
If engine rpm is too high or you release the
clutch lever too quickly, your motorcycle
may lurch forward.
5.When you attain a moderate speed, close the
throttle, pull the clutch lever in, and raise the
shift lever. After shifting, release the clutch
lever and apply the throttle.

Shifting Gears
6.To continue shifting up to each higher gear,
repeat step 5.
7.To shift down to a lower gear, close the
throttle, pull the clutch lever in, and depress
the shift lever. After shifting, release the
clutch lever and apply the throttle.
Remember to close the throttle and pull the
clutch lever in completely before shifting.
Improper shifting may damage the engine,
transmission, and drive train.
Learning when to shift gears comes with
experience. Upshift to a higher gear or reduce
throttle before engine rpm (speed) gets too
high. Downshift to a lower gear before you feel
the engine laboring (lugging) at low rpm.
Downshifting can help slow your motorcycle,
especially on downhills. However, downshifting
when engine rpm is too high can cause engine
damage.
To prevent transmission damage, do not coast
or tow the motorcycle for long distances with
the engine off.

36
Basic Operation & Riding
Braking
To slow or stop, apply the front brake and rear
brake smoothly, while downshifting to match
your speed. Gradually increase braking as you
feel the brakes slowing your speed. To prevent
stalling the engine, pull the clutch lever in
before coming to a complete stop. For support,
put your left foot down first, then your right
foot when you have finished using the rear
brake.
For maximum braking, close the throttle and
firmly apply the brake lever and pedal controls.
Applying the brakes too hard may cause the
wheels to lock and slide, reducing control of
your motorcycle. If this happens, release the
brake controls, steer straight ahead until you
regain control, then reapply the brakes more
gently.
Generally, reduce your speed or complete
braking before beginning a turn. Avoid braking
or closing the throttle quickly while turning.
Either action may cause one or both wheels to
slip. Any wheel slip will reduce your control of
your motorcycle.
When riding in wet or rainy conditions, or on
loose surfaces, the ability to maneuver and stop
will be reduced. All of your actions should be
smooth under these conditions. Rapid
acceleration, braking or turning may cause loss
of control. For your safety, exercise extreme
caution when braking, accelerating, or turning.

37
Braking
When descending a long, steep grade, use
engine compression braking by downshifting,
with intermittent use of both brakes.
When you brake to a stop, pull the clutch lever
in before stopping completely to prevent
stalling the engine. For support, put your left
foot on the ground first, then your right foot
when you have finished braking.

The Importance of Maintenance
A well-maintained motorcycle is essential for
safe, economical, and trouble-free riding. It
will also help reduce air pollution. Careful
preride inspections and good maintenance are
especially important because your motorcycle
is designed to be ridden over rough off-road
terrain.
To help you properly care for your motorcycle,
this section of the manual provides a
Maintenance Schedule. The service intervals in
this schedule are based on average riding
conditions.
More frequent service is needed if you subject
your motorcycle to severe use (such as
competition) or ride in unusually wet or dusty
areas.
Frequent servicing of the air cleaner is
especially important to help you avoid a
possible costly engine repair.
If your motorcycle overturns or is involved in a
crash, be sure your dealer inspects all major
parts, even if you are able to make some repairs.
Improperly maintaining this motorcycle
or failing to correct a problem before
you ride can cause a crash in which
you can be seriously hurt or killed.
Always follow the inspection and
maintenance recommendations and
schedules in this owner’s manual.

Maintenance Safety
The maintenance section includes instructions
on how to perform some important
maintenance tasks. Some of the most important
safety precautions follow. However, we cannot
warn you of every conceivable hazard that can
arise in performing maintenance. Only you can
decide whether or not you should perform a
given task.
• Make sure the engine is off before you begin
any maintenance or repairs.
This will help eliminate several potential
hazards:
Carbon monoxide poisoning from engine
exhaust. Be sure there is adequate
ventilation whenever you operate the engine.
Burns from hot motorcycle parts. Let the
engine and exhaust system cool before
touching.
Injury from moving parts. Do not run the
engine unless instructed to do so.

Maintenance Safety
• Read the instructions before you begin, and
make sure you have the tools and skills
required.
• To help prevent the motorcycle from falling
over, park it on a firm, level surface, using
the side stand or a maintenance stand to
provide support.
• To reduce the possibility of a fire or
explosion, be careful when working around
gasoline. Use only a non-flammable (high
flash point) solvent such as kerosene–not
gasoline–to clean parts. Keep cigarettes,
sparks, and flames away from all fuel related
parts.
• Remember that your dealer knows your
motorcycle best and is fully equipped to
maintain and repair it. To ensure the best
quality and reliability, use only new Honda
Genuine Parts or their equivalents for repair
and replacement. If you have the tools and
skills required for additional maintenance
jobs, you can purchase an official Honda
Service Manual (page 162).

Maintenance Schedule
To maintain the safety and reliability of your
motorcycle, regular inspection and service is
required as shown in the Maintenance Schedule
that follows.
The Maintenance Schedule lists items that can
be performed with basic mechanical skills and
hand tools. Procedures for these items are
provided in this manual.
The Maintenance Schedule also includes
items that involve more extensive procedures
and may require special training, tools, and
equipment. Therefore, we recommend that
you have your dealer perform these tasks
unless you have advanced mechanical skills
and the required tools. Procedures for items
in this schedule are provided in a service
manual available for purchase from your
dealer (page 162).
Because your motorcycle does not have an
odometer, service intervals in the maintenance
schedules are expressed in terms of riding days
as well as miles. To avoid overlooking required
service, we urge you to develop a convenient
way to record the number of days and/or miles
you ride.
If you do not feel capable of performing a given
task or need assistance, remember that your
Honda dealer knows your motorcycle best and
is fully equipped to maintain and repair it.
If you decide to do your own maintenance, use
only Honda Genuine Parts or their equivalents
for repair or replacement to ensure the best
quality and reliability.

Fuel
Refer to Safety Precautions on page 45.
Your engine is designed to use any unleaded
gasoline that has a pump octane number of 86
or higher. Gasoline pumps at service stations
normally display the pump octane number. For
information on the use of oxygenated fuels, see
page 158.
Use of lower octane gasoline can cause
persistent ‘‘pinging’’ or ‘‘spark knock’’ (a
louder rapping noise) which, if severe, can lead
to engine damage. (Light pinging experienced
while operating under a heavy load, such as
climbing a hill, is no cause for concern.)
If pinging or spark knock occurs at a steady
engine speed under normal load, change brands
of gasoline. If pinging or spark knock persists,
consult your dealer.
Use only unleaded fuel in your Honda. If you
ride your Honda in a country where leaded fuel
might be available, take precautions to use only
unleaded fuel.
Never use stale or contaminated gasoline or an
oil/gasoline mixture. Avoid getting dirt, dust, or
water in the fuel tank.
Fuel Recommendation
Type unleaded

Air Cleaner
Refer to Safety Precautions on page 45.
Proper air cleaner maintenance is very
important for off-road vehicles. A dirty, water-
soaked, worn-out, or defective air cleaner will
allow dirt, dust, mud, and other impurities to
pass into the engine.
Service the air cleaner more frequently if you
ride in unusually wet or dusty areas. Your
dealer can help you determine the correct
service interval for your riding conditions.
Your motorcycle’s air cleaner has very specific
performance requirements. Use a new Honda
Genuine air cleaner specified for your model or
an air cleaner of equal quality.
Using the wrong air cleaner may result in
premature engine wear.
Proper air cleaner maintenance can prevent
premature engine wear or damage, expensive
repairs, low engine power, poor gas mileage,
and spark plug fouling.
Improper or lack of proper air cleaner
maintenance can cause poor performance and
premature engine wear.

The front brake is the hydraulic disc type. As
the brake pads wear, the brake fluid level will
drop. A leak in the system will also cause the
level to drop.
Frequently inspect the system to ensure there
are no fluid leaks. Periodically inspect the
brake fluid level and the brake pads for wear.
If the front brake lever freeplay does not feel
within the normal range while riding, check the
brake pads. If they are not worn beyond the
recommended limit (page 87), there is probably

Wheels
Refer to Safety Precautions on page 45.
Keeping the wheels true (round) and
maintaining correct spoke tension is critical to
safe motorcycle operation. During the first
100 miles (150 km), spokes will loosen more
rapidly due to the initial seating of the parts.
Excessively loose spokes may result in
instability at high speeds and the possible loss

Tires & Tubes
Refer to Safety Precautions on page 45.
To safely operate your motorcycle, the tires
must be the proper type (off-road) and size, in
good condition with adequate tread, and
correctly inflated.
The following pages give detailed information
on how and when to check your air pressure,
how to inspect your tires for wear and damage,
and our recommendations on tire repair and
replacement.
Properly inflated tires provide the best
combination of handling, tread life, and riding
comfort. Generally, underinflated tires wear
unevenly, adversely affect handling, and are
more likely to fail from being overheated.
Underinflated tires can also cause wheel
damage in rocky terrain. Overinflated tires
make your motorcycle ride harshly, are more
prone to damage from surface hazards, and
wear unevenly.
Make sure the valve stem caps are secure. If
necessary, install new caps.
Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or
killed.
Follow all instructions in this owner’s
manual regarding tire inflation and
maintenance.

Tires & Tubes
Always check air pressure when your tires are
‘‘cold.’’ If you check air pressure when your
tires are ‘‘warm’’– even if your motorcycle has
only been ridden for a few miles – the readings
will be higher. If you let air out of warm tires to
match the recommended cold pressures, the
tires will be underinflated. The correct ‘‘cold’’
tire pressures are:
If you decide to adjust tire pressures for a
particular riding condition, make changes a
little at a time.
A flat tire or blowout is inconvenient and
may even cause a crash. Take time to inspect
your tires and wheels before you ride. For
more information about handling flat tires,
see page 135.

Tires & Tubes
• Inspect carefully for bumps or bulges in the
side of the tire or the tread. Replace any tire
that has a bump or bulge.
• Look closely for cuts, slits, or cracks in the
tires. Replace a tire if you can see fabric or
cord.
• Check for rocks or other objects embedded in
the tire or tread. Remove any objects.
• Measure tread depth (1). Replace the tire
before depth at the center reaches 0.12 in
(3 mm), or any time you notice a reduction
in traction.
• Check the position of both valve stems. A
tilted valve stem indicates the tube is slipping
inside the tire or the tire is slipping on the
rim. See your dealer.
If a tube is punctured or damaged, you should
replace it as soon as possible. A repaired tube
may not have the same reliability as a new one,
and it may fail while you are riding. For
information on making a temporary repair, see
page 135.
Use a replacement tube equivalent to the
original.
We recommend that tubes be replaced by your
dealer. Replacing a tube requires removing and
reinstalling the wheel. Any time a tube is
replaced, carefully inspect the tire as described
on page 99.

Tires & Tubes
The tires that came on your motorcycle were
designed to provide a good combination of
handling, braking, durability, and comfort
across a broad range of riding conditions.
• Use a replacement tire equivalent to the
original.
• Replace the tube any time you replace a tire.
The old tube will probably be stretched and,
if installed in a new tire, could fail.
• Have the wheel balanced after a new tire is
installed.
• We recommend that tires be replaced by your
dealer.

Drive Chain
Refer to Safety Precautions on page 45.
The service life of the chain depends on proper
lubrication and adjustment. Poor maintenance
can cause premature wear or damage to the
drive chain or sprockets.
Under severe usage, or when the motorcycle is
ridden in unusually dusty or muddy areas, more
frequent maintenance will be necessary.
Before servicing your drive chain, turn the
engine OFF, lower the side stand, and check
that your transmission is in neutral.
It is not necessary to remove or replace the
drive chain to perform the recommended
service in the Maintenance Schedule.
1.Check slack in the lower drive chain (1) run
midway between the sprockets. Drive chain
slack should allow the following vertical
movement by hand:

2.Check drive chain slack at several points
along the chain. The slack should remain
constant. If it isn’t, some links may be kinked
and binding. Lubricating the chain will often
eliminate binding and kinking.
Excessive chain slack may allow the drive
chain to damage the engine cases.
3.Inspect the drive chain for:
• damaged rollers
• loose pins
• dry or rusted links
• kinked or binding links
• excessive wear
Replace the drive chain (page 108) if it has
damaged rollers, loose pins, or kinks that
cannot be freed. Lubricate the drive chain
(page 107) if it appears dry or shows signs of
rust. Lubricate any kinked or binding links
and work them free. Adjust chain slack if
needed.
4.Check the chain slider (2) for wear. If the
depth (3) of the chain slider reaches the
service limit, have your dealer replace the
chain slider.

ease of assembly, hold the chain ends against
adjacent rear sprocket teeth while inserting
the master link. Install the master link
retaining clip so that the closed end of the
retaining clip will face the direction of
forward wheel rotation.
• The master link is the most critical element
of drive chain security. Master links are
reusable, as long as they remain in excellent
condition. We recommend installing a new
master link retaining clip when the drive
chain is reassembled.
• You may find it easier to install a new chain
by connecting it to the old chain with a
master link and pulling the old chain to
position the new chain on the sprockets.

Battery
Your motorcycle has a maintenance-free type
battery. You do not have to check the battery
electrolyte level or add distilled water as you
would with a conventional-type battery.
Your battery is a maintenance-free type and can
be permanently damaged if the cap strip is
removed.
Electrical accessories use current from the
battery, even when the ignition is OFF. Limited
operation also allows the battery to discharge.
If you have electrical accessories on your
motorcycle or do not ride frequently, we
recommend that you charge the battery
frequently (see Battery Charging, page 114).
If you do not expect to ride your motorcycle for
at least two weeks, we recommend you remove

• We recommend the use of a low pressure
garden hose to wash your motorcycle. High
pressure washers (like those at coin-operated
car washes) can damage certain parts of your
motorcycle. If you use a high pressure
washer, avoid spraying the following areas:
• wheel hubs
• muffler outlet
• area under seat
• engine stop switch
• brake master cylinder
•under fuel tank
• drive chain
• throttle body
High pressure water (or air) can damage
certain parts of your motorcycle.
1.Rinse your motorcycle thoroughly with cool
water to remove loose dirt.
2.Fill a bucket with cool water. Mix in a mild,
neutral detergent, such as dish washing liquid
or a product made especially for washing
motorcycles or automobiles.
3.Wash your motorcycle with a sponge or a
soft towel. As you wash, check for heavy
grime. If necessary, use a mild cleaner/
degreaser to remove the grime.
4.After washing, rinse your motorcycle
thoroughly with plenty of clean water to
remove any residue. Detergent residue can
corrode alloy parts.

can cause dulling and water spots. As you
dry, inspect for chips and scratches.
6.Lubricate the drive chain to prevent rusting.
7.Start the engine and let it idle for several
minutes. The engine heat will help dry moist
areas.
8.As a precaution, ride at a slow speed and
apply the brakes several times. This will help
dry the brakes and restore normal braking
performance.
Refer to Safety Precautions on page 45.
When the exhaust pipe and muffler are painted,
do not use a commercially available abrasive

Tips
Preparing for a Ride
A safe and enjoyable ride begins with good
planning and preparation. Always ride with at
least one other person in case you have trouble,
and let someone know where you’re going and
when you expect to return.
Before riding in an unfamiliar area, find out in
advance if you need special permits, get maps
so you can study the terrain, and talk to other
riders who know the area. The Forest Service
and the Bureau of Land Management (USA
only), the Ministry of Natural Resources
(Canada only), riding clubs, and off-road
magazines are good sources of information.
Along with your motorcycle and riding gear,
you should take along some tools and
supplies in case you have a problem. For
some of the difficulties you might encounter,
see Taking Care of the Unexpected, which
begins on page 129.
We recommend that you always take water,
food, a first aid kit, and your owner’s manual.
Other items you should consider loading on
your truck or trailer include:
• a tool kit
• tire repair supplies and tools, tubes, and tires
• extra parts, such as a drive chain and master
links, control levers, cables, and spark plugs
• wire, duct tape, and rope
• extra gasoline

Preparing for a Ride
For safety, all refueling should be done at a gas
station on the way to the riding area or at your
base camp.
What you take with you during a ride depends
on the kind of terrain, how long you expect to
ride, how far you might go from your base
camp or help, and how experienced you or your
companions are in making repairs.
If you decide to take some tools, spare parts, or
other supplies on the trail, be sure you can carry
them safely and know how to use them. Also,
be sure to follow the loading guidelines and
weight limit (page 9).

Tips
Transporting Your Honda
If you use a truck or motorcycle trailer to
transport your Honda, we recommend that you
follow these guidelines:
• Use a loading ramp.
• Secure the motorcycle in an upright position,
using motorcycle tie-down straps. Avoid
using rope, which can loosen and allow the
motorcycle to fall over.
To secure your motorcycle, brace the front
wheel against the front of the truck bed or
trailer rail. Attach the lower ends of two straps
to the tie-down hooks on your vehicle. Attach
the upper ends of the straps to the handlebar

Transporting Your Honda
Check that the tie-down straps do not contact
any control cables or electrical wiring.
Tighten both straps until the front suspension is
compressed about half-way. Too much pressure
is unnecessary and could damage the fork seals.
Use another tie-down strap to keep the rear of
the motorcycle from moving.
We recommend that you do not transport your
motorcycle on its side. This can damage the
motorcycle, and leaking gasoline could be a
hazard.

Tips
Storing Your Honda
If you won’t be riding for an extended period,
such as during the winter, thoroughly inspect
your motorcycle and correct any problem
before storing it. That way, needed repairs
won’t be forgotten and it will be easier to get
your motorcycle running again.
For more information about storage, refer to the
Honda Winter Storage Guide, available from
your dealer (USA only).
We suggest you perform the following
procedures to keep your motorcycle in top
condition. These storage procedures will
reduce the deterioration that can occur during
storage.

Tips
You & the Environment
Owning and riding a motorcycle can be
enjoyable, but you must do your part to protect
nature. When you show respect for the land,
wildlife, and other people, you also help
preserve the sport of off-road riding.
Following are tips on how you can be an
environmentally responsible motorcycle owner.
• Tread Lightly. Stay on existing roads and
trails, avoid surfaces that are easily damaged,
and ride only in areas approved for off-road
vehicles.
• Keep the Noise Down. Loud motorcycles
can be offensive. Ride as quietly as possible,
don’t remove your spark arrester, and don’t
modify the muffler or any other part of your
air intake and exhaust systems. Such
modifications not only increase noise, they
also reduce engine performance and may be
illegal.
• Choose Sensible Cleaners. Use a
biodegradable detergent when you wash your
motorcycle. Avoid aerosol spray cleaners
that contain chlorofluorocarbons (CFCs)
which damage the atmosphere’s protective
ozone layer. Don’t throw cleaning solvents
away; see the following guidelines for proper
disposal.

Tips
127
You & the Environment
• Recycle Wastes. It’s illegal and thoughtless
to put used engine oil in the trash, down a
drain, or on the ground. Used oil, gasoline,
and cleaning solvents contain poisons that
can hurt refuse workers and contaminate our
drinking water, lakes, rivers, and oceans.
Before changing your oil, make sure you
have the proper containers. Put oil and other
toxic wastes in separate sealed containers and
take them to a recycling center. Call your
local or state office of public works or
environmental services to find a recycling
center in your area and get instructions on
how to dispose of non-recyclable wastes.

Taking Care of the Unexpected
If something goes wrong during a ride, the first
thing to do is stop as soon as you safely can. Do
not continue riding if you have a flat tire, or
you hear an unusual noise, or your motorcycle
just doesn’t feel right. If you continue riding,
you could cause more damage and endanger
your own safety.
After a stop, take time to assess the situation.
Carefully inspect your motorcycle to identify
the problem, then consider your options before
you decide what to do.
If a problem is relatively minor and you have
the tools, supplies, and skills to make a
permanent repair, you may be able to fix it on
the trail and continue riding. Or, you may be
able to make a temporary repair that allows you
to slowly ride back to your base where you can
make a permanent repair or get help.
When a problem is more serious – or you don’t
have the tools, supplies, experience, or time to
deal with it – you need to choose the safest way
to get yourself and your motorcycle back to
base. For example, if you are close enough, you
(or you and another person) might be able to
push it back.
Whatever the problem, the most important
rules are:
• Always put personal safety first.

Taking Care of the Unexpected
• If the problem is relatively minor and you
have the tools, supplies, and skills to make a
temporary repair, be sure to have permanent
repairs made as soon as possible.
• Do not continue riding if you are hurt or your
motorcycle is not in safe riding condition.
Additional recommendations for specific
problems follow.
Proper operation and maintenance can prevent
starting and engine performance problems. In
many cases, the cause of the problem may be a
simple operational oversight.
If you have a problem starting the engine – or
experience poor engine performance – the
following information may help you. If you
can’t correct the problem, see your dealer.
If your motorcycle won’t start, listen as you
press the start button. If you don’t hear the
starter motor turning, refer to the Starter motor
doesn’t operate symptom. If you can hear the
starter motor working normally, refer to the
Starter motor works, but the engine won’t start

Taking Care of the Unexpected
How you handle a flat tire on the trail depends
on how serious the tube or tire damage is, and
what tools and supplies you have with you.
If you have a slow leak or a minor puncture,
there are two ways to try making a temporary
repair:
• Use an aerosol tire sealer to seal the puncture
and inflate the tube. (This can be done
without removing the tire or wheel.)
• Use a tube patch kit to repair the puncture.
(This requires removing the tire.)
If the leak is more serious, or a temporary
repair doesn’t hold, the tube must be replaced.
The tire will also need to be replaced if it is
damaged (page 101). Replacing a tube or tire
involves removing and re-installing the wheel
(pages 94, 96).

If you are unable to repair a flat tire on the trail,
you will need to push the motorcycle back to
your base or send for help. We strongly
recommend that you do not try to ride with a
flat tire. The motorcycle will be hard to handle,
and if the tire comes off the rim, it may lock up
the wheel and cause you to crash.
All of the electrical circuits on your motorcycle
have a fuses to protect them from damage
caused by excess current flow (short circuit or
overload).
If something electrical on your motorcycle
stops working, the first thing you should check
for is a blown fuse.
Check the fuses before looking elsewhere for
another possible cause of the problem. Replace
any blown fuse and check component
operation.
Riding your motorcycle with a
temporary tire repair can be risky.
If the temporary repair fails, you can
crash and be seriously injured or killed.
If you must ride with a temporary tire
repair, ride slowly and carefully until the
tire is permanently repaired or
replaced.

Taking Care of the Unexpected
Personal safety is your first priority after a
crash. If you or anyone else has been injured,
take time to assess the severity of the injuries
and whether it is safe to continue riding. If you
cannot ride safely, send someone for help. Do
not ride if you will risk further injury.
If you decide that you are capable of riding
safely, first evaluate the condition of your
motorcycle. If the engine is still running, turn it
off and look it over carefully; inspect it for fluid
leaks, check the tightness of critical nuts and
bolts, and secure such parts as the handlebar,
control levers, brakes, and wheels.
If there is minor damage, or you are unsure
about possible damage but decide to try riding
the motorcycle back to your base, ride slowly
and cautiously.
Sometimes, crash damage is hidden or not
immediately apparent. When you get home,
thoroughly check your motorcycle and correct
any problems you find. Also, be sure to have
your dealer check the frame and suspension
after any serious crash.

The drive chain, master link, brake lever or
pedal, control cables, and other components
can be damaged as you ride in dense brush or
over rocky terrain. Making a trailside repair
depends on how serious the damage is and what
tools and supplies you have with you.
• If the chain breaks or does other damage
when it comes off, you may not be able to
make a trailside repair.
• If the drive chain comes off because the
master link clip gets knocked off, you may be
able to put the chain back on with a new
master link. However, if the chain breaks or
does other damage when it comes off, you
may not be able to make a trailside repair.
• If any component of the front brake system is
damaged, you may be able to ride carefully
back to your base using the rear brake for
slowing or stopping.
• If the clutch lever breaks, you may be able to
temporarily switch the front brake lever to
the clutch side, then ride carefully back to
base using the rear brake for slowing or
stopping.
• If you damage a throttle cable or other
critical component, your motorcycle may be
unsafe to ride. Carefully assess the damage
and make any repairs that you can. But if
there is any doubt, it’s best to be conservative
and safe.

Emission Control Systems
Source of Emissions
The combustion process produces carbon
monoxide (CO), oxides of nitrogen (NOx), and
hydrocarbons (HC). Control of hydrocarbons
and oxides of nitrogen is very important
because, under certain conditions, they react to
form photochemical smog when subjected to
sunlight. Carbon monoxide does not react in
the same way, but it is toxic.
Honda Motor Co., Ltd. utilizes various systems
to reduce carbon monoxide, oxides of nitrogen
and hydrocarbons.
Exhaust Emission Control System
The exhaust emission control system includes a
PGM-FI system. No adjustment to this system
should be made although periodic inspection of
the components is recommended. The exhaust
emission control system is separate from the
crankcase emission control system.
Evaporative Emission Control System
(AC type only)
An evaporative emission control system uses
pressure proof fuel tank and fuel fill cap which
maintains inside of the fuel tank at a high
pressure to keep fuel vapor in itself while the
engine is off.
An add-on or modified part must be compliant
with applicable ARB evaporative emission
control standards. A violation of this
requirement is punishable by civil and/or
criminal punishment.
Crankcase Emission Control System
The engine is equipped with a closed crankcase
system to prevent discharging crankcase
emissions into the atmosphere. Blow-by gas is
returned to the combustion chamber through air
cleaner and throttle body.

Emission Control Systems
Problems that May Affect Motorcycle
Emissions
If you are aware of any of the following
symptoms, have the vehicle inspected and
repaired by your Honda Motorcycle Dealer:
1.Hard starting or stalling after starting
2.Rough idle
3.Misfiring or backfiring during acceleration
4.After-burning (backfiring)
5.Poor performance (driveability) and poor
fuel economy
Federal regulations prohibit removing or
disabling a device or element of design that
may affect your engine’s emission performance
unless your motorcycle will be used
exclusively in competition. If you modify your
engine for use in sanctioned competition
events, you must deface or destroy the emission
control information label.
If you loan, sell, or give your competition
modified motorcycle to someone else,
according to applicable law, you must inform
the new owner/operator in writing that the
vehicle is to be used for competition only.
Fuel Permeation Emission Control System
This vehicle complies with the Fuel Permeation
Emission Control regulations of the U.S.
Environmental Protection Agency (EPA), the
California Air Resources Board (CARB), and
Environment and Climate Change Canada
(ECCC).
The fuel tank, fuel hoses, and fuel vapor charge
hoses used on this vehicle incorporate fuel
permeation control technologies.
Tampering with the fuel tank, fuel hoses, or
fuel vapor charge hoses to reduce or defeat the
effectiveness of the fuel permeation
technologies is prohibited by federal
regulations.

Technical Information
Oxygenated Fuels
Some conventional gasolines are being blended
with alcohol or an ether compound. These
gasolines are collectively referred to as
oxygenated fuels. To meet clean air standards,
some areas of the United States and Canada use
oxygenated fuels to help reduce emissions.
If you use an oxygenated fuel, be sure it is
unleaded and meets the minimum octane rating
requirement.
Before using an oxygenated fuel, try to confirm
the fuel’s contents. Some states/provinces
require this information to be posted on the
pump.
The following are the EPA-approved
percentages of oxygenates:
ETHANOL (ethyl or grain alcohol) up to 10%
by volume.
You may use gasoline containing up to 10%
ethanol by volume. Gasoline containing
ethanol may be marketed under the name
‘‘Gasohol’’.
METHANOL (methyl or wood alcohol) up to
5% by volume.
You may use gasoline containing up to 5%
methanol by volume as long as it contains
cosolvents and corrosion inhibitors to protect
the fuel system. Gasoline containing more than
5% methanol by volume may cause starting
and/or performance problems. It may also
damage metal, rubber, and plastic parts of your
fuel system.

Oxygenated Fuels
If you notice any undesirable operating
symptoms, try another service station or switch
to another brand of gasoline.
Fuel system damage or performance problems
resulting from the use of an oxygenated fuel
containing more than the percentages of
oxygenates mentioned above are not covered
under warranty.
Oxygenated fuels can damage paint and plastic.
Be careful not to spill fuel when filling the fuel
tank. Wipe up any spills immediately.
Oxygenated fuels can damage paint and
plastic. Damage caused by spilled fuel is not
covered under warranty.

Please read this booklet and be aware of the
responsibilities, restrictions, and exclusions
which apply.
Please also keep your Honda owner’s card with
your Warranties Booklet.
Canada: Please refer to the Warranty Booklet
posted on our website at www.honda.ca.
It is important to realize that your warranty for
your Honda applies to defects in material or
factory workmanship. Your warranty coverage
does not apply to normal wear or deterioration
associated with using the motorcycle.
Your warranty coverage will not be voided if
you choose to perform your own maintenance.
However, you should have the proper tools and
service information and be mechanically
qualified. Failures that occur due directly to
improper maintenance or lack of maintenance
are not covered.

Warranty Service
Please remember that recommended
maintenance interval servicing is not included
in your warranty coverage. Additionally, your
warranty does not apply to the normal wear of
items (such as brakes, tires, etc.).
If you believe you have a problem with your
Honda, call the service department of your
dealer. Make an appointment for an inspection
and diagnosis. Remember, as the owner of the
motorcycle, you will be asked to authorize that
inspection. Your dealer will give you the results
of the inspection. If the problem is covered
under warranty, your dealer will perform the
warranty repairs for you.
If you have questions about warranty coverage
or the nature of the repair, it is best to talk to the
Service Manager of your dealer.
Sometimes, in spite of the best intentions of all
concerned, a misunderstanding may occur. If
you aren’t satisfied with your dealer’s handling
of the situation, we suggest you discuss your
problem with the appropriate member of the
dealership’s management team. If the problem
has already been reviewed with the Service
Manager, Parts Manager, Sales Manager, etc.,
contact the Owner of the dealership or his
designated representative.

Quick Reference
Quick Reference
The following is a brief, but important
collection of information you need to know
about your Honda. You’ll also find space to
record important notes.
Your Honda engine can be the most expensive
component to repair. Proper maintenance,
especially the use of the recommended fluids
and filters, prevents premature wear and
damage.
Frequent causes of costly engine repairs are:
• Engine oil -- insufficient quantity, improper
oil.
• Air cleaner -- dirty, cleaned but not oiled,
leaking because of improper installation
(poor seal).
Frequent causes of costly chassis repair are:
• Chain -- A loosely adjusted chain or a chain
stretched because of lack of lubrication may
come off and damage an engine case or
wheel hub.
• Spokes -- Loose spoke may break and
damage the wheel hub or rim.
