Introduction
Introduction
Congratulations on choosing your Honda ATV.
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 ATV for off-road use by
one rider only.
Before riding, take time to get acquainted with your ATV and how it
works. To protect your investment, we urge you to take
responsibility for keeping your ATV well maintained. Scheduled
service is a must, of course. But it’s just as important to observe the
break-in guidelines, and perform all pre-ride and other periodic
checks detailed in this manual.
We also recommend that you read this 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 225) thoroughly so you
understand the coverages that protect your new Honda and are
aware of your rights and responsibilities.
Whenever you ride, tread lightly. By staying on established trails and
riding only in approved areas, you help protect the environment and
keep off-road riding areas open for the future.

Important Safety Information
Ride Off-road Only
Your ATV is designed and manufactured for off-road use only. The
tires are not made for pavement, and the ATV 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 ATV
across.
Take Time to Learn & Practice
Even if you have ridden other ATVs, take time to become familiar
with how this ATV works and handles. Practice in a safe area until
you build your skills and get accustomed to the ATV’s size and
weight.
Because many crashes involve inexperienced or untrained riders, we
urge all riders to take an ATV operator course approved by the ATV
Safety Institute (ASI). See page 46.
Contact an authorized ATV dealer or call 1-800-887-2887 to find
out about the training courses nearest you.
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.

Important Safety Information
Ride within Your Limits
Pushing limits is another major cause of ATV 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.
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 ATV 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 ATV before every ride and perform all
recommended maintenance.

Safety Labels
Your ATV comes with a hang tag and several labels containing
important safety information. Anyone who rides the vehicle should
read and understand this information before riding.
The labels should be considered permanent parts of the vehicle. If a
label comes off or becomes hard to read, contact your dealer for
replacements.

Are You Ready to Ride?
Before you ride your ATV for the first time, we urge you to:
• Read this owner’s manual and the labels on your ATV carefully.
• Make sure you understand all the safety messages.
• Know how to operate all the controls.
Before each ride, be sure:
• You feel well and are in good physical and mental condition.
• You are wearing an approved motorcycle helmet (with chin strap
tightened securely), eye protection, and other protective
clothing.
• You don’t have any alcohol or drugs in your system.
For your safety, we strongly recommend that you always wear an
approved motorcycle helmet, eye protection, boots, gloves, long
pants, and a long-sleeved shirt or jacket whenever you ride.
Although complete protection is not possible, wearing proper gear
can reduce the chance of injury when you ride.
The following are suggestions to help you choose the proper gear.
Helmet 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 securely.

Is Your ATV Ready to Ride?
Before each ride, it’s important to inspect your ATV and make sure
any problem you find is corrected. A pre-ride inspection is a must,
not only for safety, but because having a breakdown, or even a flat
tire, can be a major inconvenience.
If your ATV has overturned or been involved in a collision, do not ride
the vehicle until it has been inspected by your dealer. There may be
damage or other problems you cannot see.
Check the following items before you get on the ATV:

Load Limits & Guidelines
Your Honda was designed as a rider-only ATV. It was not designed
to carry a passenger. It can carry cargo on the cargo racks, however,
carrying cargo anywhere else or carrying a passenger could interfere
with your balance and control of the ATV.
In addition, exceeding the weight limits or carrying an unbalanced
load can seriously affect your ATV’s handling, braking and stability.
Adding accessories or making modifications that change this ATV’s
design and performance can also make it unsafe. Also, the weight of
any accessories will reduce the maximum load the ATV can carry.
More specific information on load limits, accessories, and
modifications follows.
How much weight you put on your ATV, and how you load it, are
important to your safety. If you decide to carry cargo, you should be
aware of the following information.

Accessories & Modifications
We strongly advise you not to remove any original equipment or
modify your ATV in any way that would change its design or
operation. Such changes could seriously impair your ATV’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 your ATV illegal in
your area.
Removing or modifying your lights, exhaust system, emission control

Safe Riding Precautions
You should never ride your ATV on public streets, roads or highways,
even if they are not paved. Drivers of street vehicles may have difficulty
seeing and avoiding you, which could lead to a collision. In many states
it is illegal to operate ATVs on public streets, roads and highways.
Always keep both hands on the handlebars and both feet on the footpegs
when riding your ATV. This is important to maintain your balance and to
control the vehicle. Removing even one hand from the handlebars or one
foot from the footpegs can reduce your ability to control the ATV or could
cause you to lose your balance and fall off the ATV.

Shifting Gears
Your ATV has three shift lever positions: neutral (N), drive (D), and
reverse (R).
Neutral (N)
Use neutral when you start and warm up the engine, or if it is
necessary to stop briefly with the engine idling.
Drive (D)
Use this position for normal riding. The following two modes can be
selected in the drive position; automatic shift (AUTO) mode and
manual shift (ESP) mode.
You can select the desired mode with the drive mode select switch
(page 30).
Automatic shift (AUTO) mode:
Use this mode for everyday riding. The transmission automatically
adjusts to keep the engine at the best speed for riding conditions.
The gear position indicator shows “D” and the drive mode indicator
disappears.
Manual shift (ESP) mode:
In this mode, you can shift gears much like a manual transmission,
but without operating a clutch.
You can select three forward shift positions by operating the shift
switches; 1, 2, and 3.
The gear position indicator shows the selected position and the drive
mode indicator shows “ESP.”
When you tow a trailer, select the 1st shift position for proper
performance.

Braking
Your ATV is equipped with disc brakes on both front wheels which
are hydraulically activated by operating the right brake lever. The
single disc brake of the rear drivetrain is hydraulically activated by
pressing down on the brake pedal and mechanically activated by
operating the left brake lever.
Although the front and rear brakes have separate controls, all four
wheels are interconnected when your ATV is in the 4WD mode. So
operating any brake control in the 4WD mode will cause braking at
both the front and rear wheels.
As a general rule, the front braking system provides about 70
percent of total stopping power.
For full braking effectiveness, use both the pedal and lever
simultaneously. Using both braking systems will stop your ATV faster
with greater stability.
To slow or stop, apply the brake lever and brake pedal smoothly, while
downshifting to match your speed when your ATV is in the ESP mode.
Gradually increase braking as you feel the brakes slowing your
speed. The increase in engine compression from downshifting will
help slow your vehicle when your ATV is in the ESP mode.
Applying the brakes too hard may cause the wheels to lock and slide,
reducing control of your ATV. If this happens, release the brake
controls, steer straight ahead until you regain control, then reapply
the brakes more gently.
When possible, reduce your speed or complete braking before
entering a turn. Avoid braking or closing the throttle quickly while
turning. Either action may cause one or more wheels to slip and
reduce your control of your ATV.

Riding Your ATV
The terrain surface can be a major factor affecting turns. Skidding
during a turn is more likely to occur on slippery surfaces, such as
snow, ice, mud and loose gravel. If you skid on ice, you may lose all
directional control. To avoid skidding on slippery terrain, keep your
speed low and ride with caution.
If your ATV skids sideways during a turn, steer in the direction of the
skid. Avoid hard braking or accelerating until you have regained
directional control.

Riding Your ATV
The ATV’s ability to safely climb hills largely depends on the rider’s
skill and judgment. Begin by practicing on smooth, gentle slopes. As
you gain experience, you’ll learn the hazards and your own
limitations. You may then proceed to ride on more difficult terrain.
However, you must be able to decide which hills or hazards might
cause the ATV to overturn. Avoid excessively steep hills.
When climbing hills, you must shift weight toward the front wheels
to help keep them on the ground. To do this, shift your body slightly
forward on the seat and lean forward. For greater weight shift, move
your body farther forward and lean forward.
Riding Up Hills

Riding Your ATV
When you’ve selected a safe downhill path, shift into a lower gear (in
the ESP mode), shift your weight back with your arms extended and
braced against the handlebar, then go down slowly with the throttle
closed.
Use mainly the rear brake to control speed. Avoid using either the
front brake or rear brake hard or abruptly when riding down hills.
Remember that operating any brake control in the 4WD mode will
cause braking at both the front and rear wheels.
Remember, braking effectiveness is reduced on any hill with a loose
surface.
Riding on hills or slopes is different from riding on level terrain. Be
careful when riding on any hill. Make sure that you practice on
gentle, smooth slopes before attempting to ride on steeper or more
difficult terrain.

Crossing Hills or Slopes
• To maintain balance and stability when riding across a slope, you
need to shift weight toward the uphill side of the vehicle. To do
this, move your body off the center of the seat and lean toward
the uphill side.
• On a slippery or loose surface, you may also need to steer slightly
uphill to maintain a straight course across the slope.
• Avoid crossing hills that are excessively steep, slippery or rough.
Making Turns on Slopes
• Compared to riding on level ground, you may need to shift more
weight and lean more when making turns on slopes.
• Do not make turns on any slopes until you have first mastered the
techniques for making turns on level terrain.

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.
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 219.
Use of lower octane gasoline can cause persistent “pinging” or
“spark knock” (a loud 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.
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
pump octane number 86 (or higher)

Engine Oil & Filter
Engine oil quality is a major factor that affects both the performance
and the service life of the engine.
Using the proper oil (page 117) and filter, and regularly checking,
adding, and changing oil will help extend your engine’s life. Even the
best oil wears out. Changing oil helps get rid of dirt and deposits in
the engine. Operating the engine with old or dirty oil can damage
your engine. Running the engine with insufficient oil can cause
serious damage to the engine and transmission.
Change the engine oil as specified in the maintenance schedule on
page 104. When running in very dusty conditions, oil changes
should be performed more frequently than specified in the
maintenance schedule.

Tires
Refer to Safety Precautions on page 101.
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. Overinflated tires make your ATV ride harshly, are
more prone to damage from surface hazards, and wear unevenly.
Make sure the air valve stem caps are secure. If necessary, install new
caps.

Always check air pressure when your tires are “cold.” If you check air
pressure when your tires are “warm” – even if your ATV 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 tire pressures,
the tires will be underinflated. Be sure to check tire pressure at the

Appearance Care
Frequent cleaning and polishing will keep your Honda looking newer longer.
Frequent cleaning also identifies you as an owner who values his ATV.
A clean ATV is also easier to inspect and service.
Refer to Safety Precautions on page 101.
• To clean your ATV, you may use:
–water
– Hondabrite
– a mild, neutral detergent and water
– a mild spray and wipe cleaner/polisher
– a mild spray and rinse cleaner/degreaser and water
• Avoid products that contain harsh detergents or chemical
solvents that could damage the metal, paint, and plastic, and
camouflage coating on your ATV (Honda SxS).
• If your ATV is still warm from recent operation, give the engine
and exhaust system time to cool off.
• Park in a shady area. Washing your ATV in bright sunlight may
cause the finish to fade because water droplets intensify the sun’s
brightness.
• Spotting is also more likely because surface water can dry before
you have time to wipe it off.
• Clean your ATV regularly to protect surface finishes.
• We recommend the use of a low pressure garden hose to wash
your ATV. High pressure washers (like those at coin-operated car
washers) can damage certain parts of your ATV.
NOTICE
High pressure water (or air) can damage certain parts of your ATV.
Water entering the muffler may damage the oxygen sensor.
• After cleaning, inspect for damage, wear, and leaks (fuel, oil,
coolant and brake fluid).

1.
Cover or plug the exhaust outlet prior to washing your ATV.
2.
Rinse your ATV thoroughly with cool water to remove loose dirt.
3.
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.
4.
Wash your ATV with a sponge or soft towel. As you wash, check
for heavy grime. If necessary, use a mild cleaner/degreaser to
remove the grime.
5.
After washing, rinse your ATV thoroughly with plenty of clean
water to remove any residue. Detergent residue can corrode alloy
parts.
6.
Dry your ATV with a chamois or a soft towel. Leaving water on
the surface to air dry can cause dulling and water spots. As you
dry, inspect for chips and scratches.
7.
Remove the cover or the plug from exhaust outlet. Then, start the
engine and let it idle for several minutes. The engine heat will
help dry moist areas.
8.
As a precaution, ride your ATV at a slow speed and apply the
brakes several times. This will help dry the brakes and restore
normal braking performance.
The headlights' inside lens may fog temporarily after washing or
while riding in the rain. This does not impact the headlight
function.
Any condensation inside the headlight should dissipate after a
few minutes of running the engine with the headlight(s) on.
However, if you see a large amount of water or ice accumulated
inside the lens(es), have your vehicle inspected by your dealer.

5.
Remove the battery and charge it fully. Store it in an area
protected from freezing temperatures and direct sunlight. Slow
charge the battery (page 168) once a month.
6.
Wash and dry your ATV. Wax all painted surfaces.
7.
Inflate the tires to their recommended pressures (page 156).
8.
Store your ATV in an unheated area, free of dampness, away
from sunlight, with a minimum of daily temperature variation.
9.
Place your ATV on blocks to lift all tires off the floor.
10.
Cover your ATV with a porous material. Avoid using plastic or
similar non-breathing, coated materials that restrict air flow and
allow heat and moisture to accumulate.
NOTICE
Do not store your ATV in upright position for extended periods of
time. The ATV should be stored with all four tires on the ground. This
can damage the vehicle and leaking gasoline can be hazardous.

You & the Environment
Owning and riding an ATV 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.
The following are tips on how you can be an environmentally
responsible ATV 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 vehicles 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 ATV. 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.
• 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 to get instructions on
how to dispose of non-recyclable wastes.

If You Have a Flat Tire
How you handle a flat tire on the trail depends on how serious the
tire damage is, and what tools and supplies you have with you.
If you have a slow leak or a minor puncture, use the plug method to
make a temporary repair. (The plug method is applied from the
outside of the tire and is the same as that for conventional tubeless
tires.)
A plug-type repair kit, available at most auto parts stores or service
stations, provides a plug, an installation tool, tire cement, and an
instruction sheet. Follow the instructions provided with the repair kit
to make a temporary repair.
As soon as possible, have the tire permanently repaired by your
dealer. Any tire that cannot be repaired should be replaced.
Whenever the ATV is to be operated far from service facilities or
available transportation, we recommend that you carry a tire pump
and a repair kit with the vehicle.
If the leak is more serious, or a temporary repair doesn’t hold, the
tire must be replaced. The tire will also need to be replaced if it is
damaged (page 161). Replacing a tire involves removing and re-
installing the wheel (page 195).
If you are unable to repair a flat tire on the trail, you will need to send
for help. We strongly recommend that you do not try to ride with a
flat tire. The ATV will be hard to handle, and if the tire comes off the
rim, it may lock up the wheel and cause you to crash.

If the High Oil/Coolant
Temperature Indicator Lights
Normally, the high oil/coolant temperature indicator will only light
momentarily when you turn the ignition ON (q). Occasionally, it may
flicker at or near idling speed.
High oil/coolant temperature may be caused by restriction of air flow
to the radiator (such as mud caked on the radiator or oil cooler),
extended idling, an oil leak, a coolant leak, a low oil level, a low
coolant level, or extended operation under adverse conditions.
If the indicator comes on while you’re riding, don’t ignore it. Pull
safely to a stop. Stop the engine as soon as it’s safe to do so, and let
it cool.
NOTICE
Continuing to ride with low oil pressure or an overheated engine can
cause serious engine damage.
• A steaming engine indicates a coolant leak. Shut the engine off
and wait until the steaming stops. Look for a leak, but don’t
touch the engine or radiator system. Let everything cool off first.
• Check for any restriction of air flow to the radiator or oil cooler.
• If there’s no obvious problem, leave the engine on so the fan and
coolant circulating system can continue working. Monitor the
high coolant temperature indicator. The indicator may turn off
after a brief stop with no load on the engine.
• Check the radiator fan.
If the fan is not working, turn the engine off. Open the fuse box
(page 200) and check the radiator fan fuse. If the fuse is blown,
replace it with the proper (same rating) spare fuse. Start the
engine. If the high coolant temperature indicator comes on and
stays on, turn the engine off.
If the radiator fan is working, visually check the coolant level in
the reserve tank, located under the rear fender. It isn’t necessary
to touch the radiator system.

If You Crash
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 you are capable of riding safely, carefully inspect your
ATV for damage and determine if it is safe to ride. Check the
tightness of critical nuts and bolts securing 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 ATV back to your base, ride slowly and
cautiously.
Sometimes, crash damage is hidden or not immediately apparent.
When you get home, thoroughly check your ATV and correct any
problems you find. Also, be sure to have your dealer check the frame
and suspension after any serious crash.

Emission Control Systems
Source of Exhaust 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 and
oxygen sensor.
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.
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 the air cleaner.

Catalytic Converter
This ATV is equipped with a three-way catalytic converter.
The catalytic converter contains precious metals that serve as
catalysts, promoting chemical reactions to convert the exhaust
gasses without affecting the metals.
The catalytic converter acts on HC, CO, and NOx. A replacement unit
must be an original Honda part or its equivalent.
The catalytic converter must operate at a high temperature for the
chemical reactions to take place. It can set fire to any combustible
materials that come near it. Park your ATV away from high grasses,
dry leaves, or other flammables.
A defective catalytic converter contributes to air pollution, and can
impair your engine’s performance. Follow these guidelines to protect
your ATV’s catalytic converter.
• Always use unleaded fuel. Even a small amount of leaded fuel
can contaminate the catalyst metals, making the catalytic
converter ineffective.
• 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 ATV.
• If your engine is misfiring, backfiring, stalling, or otherwise not
running properly, stop riding and turn off the engine. Have your
ATV serviced as soon as possible.

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 ATV, call the service
department of your dealer. Make an appointment for an inspection
and diagnosis. Remember, as the owner of the ATV, 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 their designated representative.
