A Few Words About Safety
Your safety, and the safety of others, is very
important. Operating this vehicle safely is an
important responsibility.
To help you make informed decisions about
safety, we have provided operating
procedures and other information on safety
labels and in this manual. This information
alerts you to potential hazards that could
hurt you or others.
Of course, it is not practical or possible to
warn you about all hazards associated with
operating or maintaining a vehicle. You must
use your own good judgment.
You will find important safety information in a
variety of forms, including:
● Safety labels on the vehicle
●
Safety Messages preceded by a safety alert
symbol and one of three signal words:
DANGER, WARNING, or CAUTION.
These signal words mean:
3DANGER
You WILL be KILLED or SERIOUSLY
HURT if you don’t follow instructions.
3WARNING
You CAN be KILLED or SERIOUSLY
HURT if you don’t follow instructions.
3CAUTION
You CAN be HURT if you don’t follow
instructions.
Other important information is
provided under the following titles:
NOTICE
Information to help you avoid
damage to your vehicle, other
property, or the environment.

Safety Guidelines
Follow these guidelines to enhance your safety:
● Perform all routine and regular inspections
specified in this manual.
● Stop the engine and keep sparks and flames
away before filling the fuel tank.
● Do not run the engine in enclosed or partly
enclosed areas. Carbon monoxide in
exhaust gases is toxic and can kill you.
Always Wear a Helmet
It's a proven fact: helmets and protective
apparel significantly reduce the number and
severity of head and other injuries. So always
wear an approved helmet and protective
apparel. 2 P. 9
Before Riding
Make sure that you are physically fit, mentally
focused, and free of alcohol and drugs. Check
that you and your passenger are both wearing
an approved helmet and protective apparel.
Instruct your passenger on holding onto the
seat strap or your waist, leaning with you in
turns, and keeping their feet on the footpegs,
even when the vehicle is stopped.
Take Time to Learn & Practice
Even if you have ridden other vehicles, practice
riding in a safe area to become familiar with
how this vehicle works and handles, and to
become accustomed to the vehicle's size and
weight.
We recommend that all riders take a certified
course approved by the Motorcycle Safety
Foundation (MSF) or a state approved training
course. New riders should start with the basic
course, and even experienced riders will find the
advanced course beneficial.

USA
Other riding tips can be found in the You
and Your Motorcycle Riding Tips booklet that
came with your vehicle.
Developing off-road riding skill is a gradual
step-by step process. Start by practicing at low
speeds in a safe area and slowly build your
skills.
Ask your dealer if there are off-road riding
groups in your area where you can learn from
experienced riders. Also be sure to read Tips &
Practice Guide for the Off-Highway Motorcyclist
that came with your new vehicle.
Ride Defensively
Always pay attention to other vehicles around
you, and do not assume that other drivers see
you. Be prepared to stop quickly or perform an
evasive maneuver.
Make Yourself Easy to See
Make yourself more visible, especially at night,
by wearing bright reflective clothing, positioning
yourself so other drivers can see you, signaling
before turning or changing lanes, and using
your horn when necessary.
Be Alert for Off-road Hazards
The terrain can be 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
Never ride beyond your personal abilities or
faster than conditions warrant. Fatigue and
inattention can impair your ability to use good
judgment and ride safely.
Safety Guidelines
Vehicle Safety
4
Don't Drink or Use Drugs and Ride
Alcohol or drugs and riding don't mix. Even one
alcoholic drink can reduce your ability to
respond to changing conditions, and your
reaction time gets worse with every additional
drink. The same is true for drug use. Don't drink
or use and ride, and don't let your friends do it
either.
Keep Your Honda in Safe Condition
It's important to keep your vehicle properly
maintained and in safe riding condition.
Having a breakdown can be difficult, especially
if you are stranded off-road far from your base.
Inspect your vehicle before every ride and
perform all recommended maintenance. Never
exceed load limits (2 P. 17), and do not modify
your vehicle or install accessories that would
make your vehicle unsafe (2 P. 15).
If You are Involved in a Crash
Personal safety is your first priority. 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. Call for emergency
assistance if needed. Also follow applicable laws
and regulations if another person or vehicle is
involved in the crash.
If you decide to continue riding, first turn the
ignition switch to the OFF position, and evaluate
the condition of your vehicle. Inspect for fluid
leaks, check the tightness of critical nuts and
bolts, and check the handlebar, control levers,
brakes, and wheels. Ride slowly and cautiously.
Your vehicle may have suffered damage that is
not immediately apparent. Have your vehicle
thoroughly checked at a qualified service facility
as soon as possible.

Carbon Monoxide Hazard
Exhaust contains poisonous carbon monoxide, a
colorless, odorless gas. Breathing carbon
monoxide can cause loss of consciousness and
may lead to death.
If you run the engine in a confined or even
partly enclosed area, the air you breathe could
contain a dangerous amount of carbon
monoxide.
Never run your vehicle inside a garage or other
enclosure.
3WARNING
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.
Only run your vehicle's engine when it
is located in a well ventilated area
outdoors.

Safety Labels
Safety and information labels on your vehicle
provide important safety information and may
warn you of potential hazards that could cause
serious injury. Read these labels carefully and
don't remove them.
If a label comes off or becomes hard to read,
contact your dealer for a replacement.

Safety Precautions
● Ride cautiously and keep your hands on the
handlebar and feet on the footpegs.
● Instruct your passenger to keep their hands
on the seat strap or your waist and their feet
on the footpegs while riding.
● Always consider the safety of your
passenger, as well as other drivers and
riders.
Protective Apparel
Make sure that you and any passenger are
wearing an approved helmet, eye protection,
and high-visibility protective clothing. Avoid
wearing loose clothes that could get caught on
any part of the vehicle. Ride defensively in
response to weather and road conditions.
#
Helmet
Should be safety-standard certified, high-
visibility, and the correct size for your head.
● Must fit comfortably but securely, with the
chin strap fastened
● Face shield with unobstructed field of vision
or other approved eye protection
USA
Look for a DOT (Department of
Transportation) certification label on any helmet
you buy.
3WARNING
Not wearing a helmet increases the
chance of serious injury or death in a
crash.
Make sure that you and any passenger
always wear an approved helmet and
protective apparel.

Riding Precautions
Break-in Period
During the first 300 miles (500 km) of running,
follow these guidelines to ensure your vehicle's
future reliability and performance.
● Avoid full-throttle starts and rapid
acceleration.
● Avoid hard braking and rapid down-shifts.
● Ride conservatively.
Brakes
Observe the following guidelines:
● Avoid excessively hard braking and
downshifting.
u Sudden braking can reduce the vehicle's
stability.
u Where possible, reduce speed before
turning; otherwise you risk sliding out.
● Exercise caution on low traction surfaces.
u The tires slip more easily on such
surfaces and braking distances are
longer.
● Avoid continuous braking.
u Repeated braking, such as when
descending long, steep slopes can
seriously overheat the brakes, reducing
their effectiveness. Use engine braking
with intermittent use of the brakes to
reduce speed.
● For full braking effectiveness, operate both
the front and rear brakes together.
Riding Precautions
Vehicle Safety
11
Continued
#
Anti-lock Brake System (ABS)
CRF300LA/LDA
This model is equipped with an Anti-lock Brake
System (ABS) designed to help prevent the
brakes from locking up during hard braking.
● ABS does not reduce braking distance. In
certain circumstances, ABS may result in a
longer stopping distance.
● ABS does not function at speeds below 6
mph (10 km/h).
● The brake lever and pedal may recoil slightly
when applying the brakes. This is normal.
● Always use the recommended front/rear
tires and sprockets to ensure correct ABS
operation.
#
Engine Braking
Engine braking helps slow your vehicle down
when you release the throttle. For further
slowing action, downshift to a lower gear. Use
engine braking with intermittent use of the
brakes to reduce speed when descending long,
steep slopes.
#
Wet or Rainy Conditions
Road surfaces are slippery when wet, and wet
brakes further reduce braking efficiency.
Exercise extra caution when braking in wet
conditions.
If the brakes get wet, apply the brakes while
riding at low speed to help them dry.
Riding Precautions
Vehicle Safety
12
Parking
● Park on a firm, level surface.
● If you must park on a slight incline or loose
surface, park so that the vehicle cannot
move or fall over.
● Make sure that high-temperature parts
cannot come into contact with flammable
materials.
● Do not touch the engine, muffler, brakes
and other high-temperature parts until they
cool down.
● To reduce the likelihood of theft, always lock
the handlebar and remove the key when
leaving the vehicle unattended.
Use of an anti-theft device is also
recommended.
#
Parking with the Side Stand
1.
Stop the engine.
2.
Push the side stand down.
3.
Slowly lean the vehicle to the left until its
weight rests on the side stand.
4.
Turn the handlebar fully to the left.
u Turning the handlebar to the right
reduces stability and may cause the
vehicle to fall.
5.
Turn the ignition switch to the LOCK
position and remove the key. 2 P. 44

Refueling and Fuel Guidelines
Follow these guidelines to protect the engine,
fuel system and catalytic converter:
● Use only unleaded gasoline.
● Use the recommended octane number.
Using lower octane gasoline will result in
decreased engine performance.
● Do not use fuels containing a high
concentration of alcohol. 2 P. 123
● Do not use stale or contaminated gasoline
or an oil/gasoline mixture.
● Avoid getting dirt or water in the fuel tank.

Accessories &
Modifications
We strongly advise that you do not add any
accessories that were not specifically designed
or approved for your vehicle by Honda or make
modifications to your vehicle from its original
design. Doing so can make it unsafe.
Modifying your vehicle may also void your
warranty and make your vehicle illegal to
operate on public roads. Before deciding to
install accessories on your vehicle, be certain
the modification is safe and legal.
3WARNING
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 accessories and
modifications.

Off-Road Safety
Learn to ride in an uncongested off-road area
free of obstacles before venturing onto
unfamiliar terrain.
● Always obey local off-road riding laws and
regulations.
● Obtain permission to ride on private
property. Avoid posted areas and obey “NO
Trespassing” signs.
● Ride with a friend on another vehicle so that
you can assist each other in case of trouble.
● Familiarity with your vehicle is critically
important should a problem occur far from
help.
● Never ride beyond your ability and
experience or faster than conditions warrant.
● If you are not familiar with the terrain, ride
cautiously. Hidden rocks, holes, or ravines
could spell disaster.
● A muffler is required in most off-road areas.
Don't modify your exhaust system.
Remember that excessive noise bothers
everyone and creates a bad image for
motorcycling.

Loading
● Carrying extra weight affects your vehicle's
handling, braking and stability.
Always ride at a safe speed for the load you
are carrying.
● Avoid carrying an excessive load and keep
within specified load limits.
Maximum weight capacity 2 P. 132
● Tie all luggage securely, evenly balanced,
and close to the center of the vehicle.
● Do not place objects near the lights or the
muffler.
Also follow these guidelines when you ride off-
road on rough terrain:
● Do not carry a passenger.
● Keep cargo small and light weight.
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.

#
Checking the Air Pressure
Visually inspect your tires and use an air
pressure gauge to measure the air pressure
before each off-road ride and whenever you
return to pavement after riding off-road. If you
only ride on pavement, check the pressure at
least once a month or any time you think the
tires look low. Always check air pressure when
your tires are cold.
If you decide to adjust the tire pressure for a
particular off-road riding condition, make
changes a little at a time.
#
Inspecting for Damage
Inspect the tires for
cuts, slits, or cracks that
expose fabric or cords,
or nails or other
foreign objects
embedded in the side
of the tire or the tread.
Also inspect for any unusual bumps or bulges in
the side walls of the tires.

#
Inspecting for Abnormal Wear
Inspect the tires for
signs of abnormal wear
on the contact surface.
#
Inspecting Tread Depth
Inspect the tread wear indicators. If they
become visible, replace the tires immediately.
For safe riding, you should replace the tires
when the minimum tread depth is reached.
#
Inspecting Rims and Valve Stems
Inspect the rims for damage and loose spokes.
Also inspect the valve stems for their positions.
A tilted valve stem indicates the tube is slipping
inside the tire or the tire is slipping on the rim.
See your dealer.
3WARNING
Riding on 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.

Have your tires replaced by your dealer.
For recommended tires, air pressure, and
minimum tread depth, see “Specifications.”
2 P. 133
Follow these guidelines whenever you replace
tires:
● Use the recommended tires or their
equivalents of the same size, construction,
speed rating, and load range.
● Remember to replace the inner tube
whenever you replace a tire. The old tube
will probably be stretched, and it could fail if
installed in a new tire.
3WARNING
Installing improper tires on your vehicle
can adversely affect handling and
stability, and can cause a crash in which
you can be seriously hurt or killed.
Always use the size and type of tires
recommended in this owner's manual.

Tire Puncture
Repairing a puncture or removing a wheel
requires special tools and technical expertise.
We recommend you have this type of service
performed by your dealer.
After an emergency repair, always have the
tire inspected/replaced by your dealer.
Tube Repair and Replacement
If a tube is punctured or damaged, you
should replace it as soon as possible. A tube
that is repaired may not have the same
reliability as a new one, and it may fail while
you are riding.
If you need to make a temporary repair by
patching a tube or using an aerosol sealant,
ride cautiously at reduced speed and have
the tube replaced before you ride again.
Anytime a tube is replaced, the tire should be
carefully inspected as described.
3WARNING
Riding your vehicle with a temporary
tire or tube 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 or
tube repair, ride slowly and carefully
and do not exceed 30 mph (50 km/h)
until the tire or tube is replaced.

Assist-slipper Clutch System
The assist-slipper clutch system helps to prevent
the rear tire from locking up when the
deceleration of your vehicle produces a strong
engine braking effect. It also makes the clutch
lever operation feel lighter.
Use only MA classification engine oil for your
vehicle. Using engine oil other than MA
classification oil could result in damage to the
assist-slipper clutch system.
Caring for Your Vehicle
Frequent cleaning and polishing is important to
ensure the life of your Honda. A clean vehicle
makes it easier to spot potential problems.
In particular, seawater and salts used to prevent
ice on roads promote the formation of
corrosion. Always wash your vehicle thoroughly
after riding on coastal or treated roads.
Washing
Allow the engine, muffler, brakes, and other
high-temperature parts to cool before washing.
1.
Rinse your vehicle thoroughly using a low
pressure garden hose to remove loose dirt.
2.
If necessary, use a sponge or a soft towel
with mild cleaner to remove road grime.

Emission Control Systems
Your vehicle engine emits combustion
byproducts, including carbon monoxide (CO),
oxides of nitrogen (NOx), and hydrocarbons
(HC). Gasoline evaporation also emits
hydrocarbons. Controlling the production of
NOx, CO, and HC is important for the
environment.
Exhaust Emission Requirements
The U.S. Environmental Protection Agency
(EPA), the California Air Resources Board
(CARB), and Environment and Climate Change
Canada (ECCC) require that your vehicle comply
with applicable exhaust, crankcase, and fuel
permeation emission standards during its useful
life, when operated and maintained according
to the instructions provided.
CARB also requires that your vehicle comply
with applicable evaporative emission
requirements during its useful life, when
operated and maintained according to the
instructions provided.
USA
Compliance with the terms of the
Distributor's Warranties for Honda Motorcycle
Emission Control Systems is necessary in order

January 1, 1983 comply with applicable noise
emission standards for one year or 3,730 miles
(6,000 km) after the time of purchase when
operated and maintained according to the
instructions provided.
Exhaust Emission Control System
The exhaust emission control system includes
the following components that should not need
adjustment, although periodic inspection by
your dealer is recommended.
#
PGM-FI System
The PGM-FI (programmed fuel injection) system
uses sequential multiport fuel injection, and is
comprised of air intake, engine control, fuel
control, and exhaust control subsystems. The
engine control module (ECM) uses sensors to
determine how much air enters the engine, and
then controls how much fuel to inject.
#
Ignition Timing Control System
The ignition timing control system adjusts the
ignition timing to reduce the amount of HC,
CO, and NOx produced.
#
Secondary Air Injection System
The secondary air injection system adds filtered
air into the exhaust gas to help improve
emission control performance.
#
Catalytic Converters
The exhaust system contains one or more
catalytic converters. Catalytic converters use a
catalyst to convert most of the harmful exhaust
gas compounds into harmless compounds.
Emission Control Systems
Information
119
Continued
Evaporative Emission Control System
50 STATE (meets California)
An evaporative emissions control system uses a
canister filled with charcoal to adsorb fuel vapor
from the fuel tank while the engine is off. The
vapor is drawn into the engine and burned
while riding.
Crankcase Emissions 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 the air cleaner and throttle
body.
Fuel Permeation Emission Control
The fuel tank, fuel hoses, and fuel vapor charge
hoses use fuel permeation control technologies
to prevent fuel vapor emissions. Tampering with
these components to reduce or defeat the
effectiveness of the fuel permeation
technologies is prohibited.
Noise Emission Control System
#
TAMPERING WITH THE NOISE CONTROL
SYSTEM IS PROHIBITED:
U. S. federal law prohibits, and Canadian
provincial laws may prohibit, the following acts
or the causing thereof: (1) The removal or
rendering inoperative by any person, other than
for purposes of maintenance, repair or
replacement, of any device or element of
design incorporated into any new vehicle for
the purpose of noise control prior to its sale or
delivery to the ultimate purchaser or while it is
in use; or (2) the use of the vehicle after such
device or element of design has been removed
or rendered inoperative by any person.

● Rough idling
● Misfiring or backfiring during acceleration
● Poor engine performance and poor fuel
economy
Emission Control Systems
Information
121
Catalytic Converter
This vehicle is equipped with a three-way
catalytic converter. The catalytic converter
contains precious metals that serve as catalysts
in high temperature chemical reactions that
convert hydrocarbons (HC), carbon monoxide
(CO), and oxides of nitrogen (NOx) in the
exhaust gases into safe compounds.
A defective catalytic converter contributes to air
pollution and can impair your engine's
performance. A replacement unit must be an
original Honda part or equivalent.
Follow these guidelines to protect your vehicle's
catalytic converter:
● Always use unleaded gasoline. Leaded
gasoline will damage the catalytic converter.
● Keep the engine in good running condition.
A poorly running engine can cause the
catalytic converter to overheat, causing
damage to the converter or the vehicle.
● If your engine is misfiring, backfiring, stalling,
or otherwise not running properly, stop
riding and turn off the engine. Have your
vehicle serviced as soon as possible.

Oxygenated Fuels
Some conventional fuels blended with alcohol
or an ether compound are available in some
locales to help reduce emissions to meet clean
air standards. These gasolines are collectively
referred to as oxygenated fuels. If you plan to
use oxygenated fuel, check that it is unleaded
and meets the minimum octane rating and
blend requirement.
The following fuel blends have been approved
for use in your vehicle:
● Ethanol (ethyl alcohol) up to 10% by volume.
u Gasoline containing ethanol may be
marketed under the name Gasohol.
● Do not use gasoline containing methanol
(methyl alcohol).
If you accidentally fill your fuel tank with an
oxygenated fuel containing higher percentages,
you may experience performance problems. To
resolve the problem, have your dealer drain the
fuel tank and replace with the correct fuel. Fuel
system or performance problems resulting from
the use of an oxygenated fuel containing higher
percentages are not covered by your warranty.
NOTICE
Improper use of oxygenated fuels can damage
metal, rubber, and plastic parts of your fuel
system.
Oxygenated fuel can also damage paint.
Damage caused by spilled fuel is not covered by

Statement on Warranty Coverage for
Aftermarket and Recycled Parts
The Magnuson-Moss Warranty Act, 15 U.S.C. s.
2301 et seq., makes it illegal for motor vehicle
manufacturers to void a motor vehicle warranty
or deny warranty coverage solely because an
aftermarket or recycled part has been used to
repair the vehicle or someone other than the
authorized service provider performed service
on the vehicle. This provision does not apply to
a new motor vehicle purchased solely for
commercial or industrial use.
Under federal law, a manufacturer may deny
warranty coverage and charge for repairs to a
vehicle if it is discovered that an aftermarket or
recycled part installed on the vehicle is defective
or was installed incorrectly and caused damage
to another part of the vehicle otherwise covered
under warranty. The Federal Trade Commission
requires that a manufacturer demonstrate that
an aftermarket or recycled part or service
performed by a person other than an
authorized service provider caused damage to
another part of the vehicle otherwise covered
under warranty before denying warranty
coverage. Additionally, federal law allows a
manufacturer to void a motor vehicle warranty
or deny warranty coverage if the manufacturer
provides the article or service to consumers free
of charge under the warranty or the
manufacturer has secured a waiver from the
Federal Trade Commission.

authorize that inspection, and your dealer will
return the results of the inspection. If a problem
exists and is covered under warranty, your
dealer will perform the warranty repairs. If you
have any questions about your warranty
coverage or the nature of the repair, talk to the
Service Manager of your Honda dealer.
If a misunderstanding occurs and 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 you are still
not satisfied, contact the owner of the
