q SAFETY INFORMATION
AN ATV IS NOT A TOY AND CAN BE HAZARDOUS TO OPERATE.
An ATV handles differently from other vehicles including motorcycles and cars. A collision or rollover
can occur quickly, even during routine maneuvers such as turning and riding on hills or over obstacles,
if you fail to take proper precautions.
SEVERE INJURY OR DEATH can result if you do not follow these instructions:
8 Read this manual and all labels carefully and follow the operating procedures described.
8 Never operate an ATV without proper training or instruction. Take a Training Course.
Beginners should receive training from a certified instructor. Contact an authorized ATV dealer or
call 1-800-887-2887 to find out about the training courses nearest you.
8 Always follow the age recommendation:
- A child under 16 years old should never operate an ATV with engine size greater than 90cc.
8 Never allow a child under age 16 to operate an ATV without adult supervision, and never allow con-
tinued use of an ATV by a child if he or she does not have the abilities to operate it safely.
8 Never carry a passenger on an ATV.
2-1

Page 14
8 Always avoid operating an ATV on any paved surfaces, including sidewalks, driveways, parking lots
and streets.
8 Never operate an ATV on any public street, road or highway, even a dirt or gravel one.
8 Never operate an ATV without wearing an approved motorcycle helmet that fits properly. You
should also wear eye protection (goggles or face shield), gloves, boots, long-sleeved shirt or jacket,
and long pants.
8 Never consume alcohol or drugs before or while operating this ATV.
8 Never operate at speeds too fast for your skills or the conditions. Always go at a speed that is prop-
er for the terrain, visibility and operating conditions, and your experience.
8 Never attempt wheelies, jumps, or other stunts.
8 Always inspect your ATV each time you use it to make sure it is in safe operating condition. Always
follow the inspection and maintenance procedures and schedules described in this manual.
8 Always keep both hands on the handlebars and both feet on the footboards of the ATV during oper-
ation.
8 Always go slowly and be extra careful when operating on unfamiliar terrain. Always be alert to
changing terrain conditions when operating the ATV.
2-2
Page 15
8 Never operate on excessively rough, slippery or loose terrain until you have learned and practiced
the skills necessary to control the ATV on such terrain. Always be especially cautious on these
kinds of terrain.
8 Always follow proper procedures for turning as described in this manual. Practice turning at low
speeds before attempting to turn at faster speeds. Do not turn at excessive speed.
8 Never operate the ATV on hills too steep for the ATV or for your abilities. Practice on smaller hills
before attempting larger hills.
8 Always follow proper procedures for climbing hills as described in this manual. Check the terrain
carefully before you start up any hill. Never climb hills with excessively slippery or loose surfaces.
Shift your weight forward. Never open the throttle suddenly. Never go over the top of a hill at high
speed.
8 Always follow proper procedures for going down hills and for braking on hills as described in this
manual. Check the terrain carefully before you start down any hill. Shift your weight backward.
Never go down a hill at high speed. Avoid going down a hill at an angle that would cause the vehicle
to lean sharply to one side. Go straight down the hill where possible.
8 Always follow proper procedures for crossing the side of a hill as described in this manual. Avoid
hills with excessively slippery or loose surfaces. Shift your weight to the uphill side of the ATV.
Never attempt to turn the ATV around on any hill until you have mastered the turning technique
described in this manual on level ground. Avoid crossing the side of a steep hill if possible.
2-3
Page 16
8 Always use proper procedures if you stall or roll backwards when climbing a hill. To avoid stalling,
maintain a steady speed when climbing a hill. If you stall or roll backwards, follow the special procedure for braking described in this manual. Dismount on the uphill side or to a side if pointed straight
uphill. Turn the ATV around and remount, following the procedure described in this manual.
8 Always check for obstacles before operating in a new area.
Never attempt to operate over large obstacles, such as large rocks or fallen trees. Always follow
proper procedures when operating over obstacles as described in this manual.
8 Always be careful when skidding or sliding. Learn to safely control skidding or sliding by practicing
at low speeds and on level, smooth terrain. On extremely slippery surfaces, such as ice, go slowly
and be very cautious in order to reduce the chance of skidding or sliding out of control.
8 Never operate an ATV in fast flowing water or in water deeper than that recommended in this manu-
al. Remember that wet brakes may have reduced stopping ability. Test your brakes after leaving
water. If necessary, apply them several times to let friction dry out the linings.
8 Always be sure there are no obstacles or people behind you when you operate in reverse. When it
is safe to proceed in reverse, go slowly.
8 Always use the size and type tires specified in this manual.
Always maintain proper tire pressure as described in this manual.
8 Never modify an ATV through improper installation or use of accessories.
2-4
Page 17
8 Never exceed the stated load capacity for an ATV. Cargo should be properly distributed and
securely attached. Reduce speed and follow instructions in this manual for carrying cargo. Allow
greater distance for braking.

WARNING
POTENTIAL HAZARD
Riding with improperly operating brakes.
WHAT CAN HAPPEN
You could lose braking ability, which
could lead to an accident.
HOW TO AVOID THE HAZARD
Always check the brakes at the start of
every ride. Do not ride the ATV if you find

Reserve: 1.3 L (0.29 Imp gal, 0.34 US gal)
5-3
Page 37
cC
Use only unleaded gasoline. The use of leaded gasoline will cause severe damage to internal engine parts, such as the valves and piston rings, as well as to the exhaust system.
Your Yamaha engine has been designed to use
regular unleaded gasoline with a pump octane
number ([R+M]/2) of 86 or higher, or research
octane number of 91 or higher. If knocking or
pinging occurs, use a different brand of gasoline
or premium unleaded fuel. Unleaded fuel will
give you longer spark plug life and reduced
maintenance cost.
Gasohol
There are two types of gasohol; gasohol containing ethanol and that containing methanol.
Gasohol containing ethanol can be used if
ethanol content does not exceed 10%. Gasohol
containing methanol is not recommended by
Yamaha because it may cause fuel system
damage or vehicle performance problems.
q
WARNING
POTENTIAL HAZARD
Improper care when refueling.
WHAT CAN HAPPEN
Fuel can spill, which can cause a fire and
severe injury.
Fuel expands when it heats up. If the fuel
tank is overfilled, fuel could spill out due

Engine break-in
There is never a more important period in the
life of your machine than the period between
zero and 20 hours.
For this reason, we ask that you carefully read
the following material. Because the engine is
brand new, you must not put an excessive load
on it for the first several hours of running. During
the first 20 hours, the various parts in the engine
wear and polish themselves to the correct operating clearances.
During this period, prolonged full throttle operation or any condition which might result in excessive engine heating must be avoided. However,
momentary (2–3 seconds maximum) full throttle
operation under load does not harm the engine.
Each full throttle acceleration sequence should
be followed with a substantial rest period for the
engine by cruising at lower r/min so the engine
can rid itself of the temporary build up of heat.
If any abnormality is noticed during this period,
consult a Yamaha dealer.
0–10 hours:
Avoid continuous operation above half throttle.
Allow a cooling off period of five to ten minutes
after every hour of operation. Vary the speed of
the machine from time to time. Do not operate it
at one set throttle position.
6-6

Accessories and loading
EBU00222
Accessories
Accessories can affect the handling and control
of your ATV. Keep the following in mind when
considering an accessory or operating an ATV
which has accessories.
8 Choose only accessories designed for your
ATV. Your Yamaha dealer has a variety of
genuine Yamaha accessories. Other accessories may also be available on the market.
However, it is not possible for Yamaha to test
all non-Yamaha accessories, nor have any
control over the quality or suitability of them.
Choose a genuine Yamaha accessory, or one
that is equivalent in design and quality.
8 Accessories should be rigidly and securely
mounted. An accessory which can shift position or come off while you are riding could
affect your ability to control the ATV.
8 Do not mount an accessory where it could
interfere with your ability to control the ATV.
Examples include (but are not limited to) a
heavy or bulky object attached to the handlebars which could make steering difficult, an
accessory that limits your ability to move
around on the seat, or one that limits your
view.
8 Use extra caution when riding an ATV with
accessories. The ATV may handle differently
than it does without accessories.

EBU14781
Loading
As originally equipped, this ATV is not designed
to carry cargo or tow a trailer. If you choose to
add accessories so that you can carry cargo or
tow a trailer, you must use common sense and
good judgment. Keep the following points in
mind:
8 Never exceed the weight limits shown. An
overloaded ATV can be unstable.
MAXIMUM LOADING LIMIT
8 Vehicle loading limit (total weight of
cargo, rider and accessories):
105 kg (231 lb)
8 Front carrier: 5 kg (11 lb)
8 Rear carrier: 10 kg (22 lb)
8 Load cargo on the carriers as close to the
center of the vehicle as possible. Put cargo at
the rear of the front carrier and at the front of
the rear carrier. Center the load from side to
side.
8 Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around.
A shifting load can cause an accident.
8 Make sure the load does not interfere with
controls or your ability to see where you are
going.
8 Ride more slowly than you would without a
load. The more weight you carry, the slower
you should go.
8 Allow more braking distance. A heavier vehi-
cle takes longer to stop.
8 Avoid making sharp turns unless at very slow
speeds.
8 Avoid hills and rough terrain. Choose terrain
carefully. Added weight affects the stability
and handling of the ATV.

Select a large, flat area off-road to become
familiar with your ATV. Make sure that this area
is free of obstacles and other riders. You should
practice control of the throttle, brakes, shifting
procedures, and turning techniques in this area
before trying more difficult terrain. Always avoid
riding on paved surfaces: the ATV is designed
for off-road use only, and handling maneuvers
are more difficult to perform on pavement.
Set the parking brake and follow the instruction
on page 6-1 to start the engine. Once it has
warmed up you are ready to begin riding your
ATV. Remember that the engine and exhaust
pipe will be hot when riding and afterwards; do
not allow skin or clothing to come in contact with
these components.
With the engine idling, return the starter knob to
the closed position and shift the drive select
lever into the forward position. Then release the
parking brake. Apply the throttle slowly and
smoothly. The centrifugal clutch will engage and
you will start to accelerate. If the throttle is
applied too abruptly, the front wheels may lift off
the ground resulting in a loss of directional control. Avoid higher speeds until you are thoroughly familiar with the operation of your ATV.
When slowing down or stopping, release the
throttle and apply the brakes smoothly and
evenly. Improper use of the brakes can cause
the tires to lose traction, reducing control and
increasing the possibility of an accident.
7-21
Page 75
TURNING YOUR ATV
To achieve maximum traction while riding offroad, the two rear wheels are mounted solidly
on one axle and turn together at the same
speed. Therefore, unless the wheel on the
inside of the turn is allowed to slip or lose some
traction, the ATV will resist turning. A special
turning technique must be used to allow the ATV
to make turns quickly and easily. It is essential
that this skill be learned first at low speed.
q
WARNING
POTENTIAL HAZARD
Turning improperly.
WHAT CAN HAPPEN
ATV could go out of control, causing a
collision or overturn.
HOW TO AVOID THE HAZARD
Always follow proper procedures for turning as described in this Owner’s Manual.
Practice turning at low speeds before
attempting to turn at faster speeds. Do not
turn at speeds too fast for your skills or
the conditions.
As you approach a curve, slow down and begin
to turn the handlebars in the desired direction.
As you do so, put your weight on the footboard
to the outside of the turn (opposite your desired
direction) and lean your upper body into the
turn. Use the throttle to maintain an even speed
through the turn. This maneuver will let the
wheel on the inside of the turn slip slightly,
allowing the ATV to make the turn properly.

Lean towards
inside of turn.
Support your
weight on the
outer footboard
This procedure should be practiced at slow
speed many times in a large off-road area with
no obstacles. If an incorrect technique is used,
your ATV may continue to go straight. If the ATV
doesn’t turn, come to a stop and then practice
the procedure again. If the riding surface is slippery or loose, it may help to position more of
your weight over the front wheels by moving forward on the seat.
Once you have learned this technique you
should be able to perform it at higher speeds or
in tighter curves.
Improper riding procedures such as abrupt throttle changes, excessive braking, incorrect body
movements, or too much speed for the sharpness of the turn may cause the ATV to tip. If the
ATV begins to tip over to the outside while negotiating a turn, lean more to the inside. It may
also be necessary to gradually let off on the
throttle and steer to the outside of the turn to
avoid tipping over.
Remember: Avoid higher speeds until you are
thoroughly familiar with the operation of your
ATV.

CLIMBING UPHILL
Use proper riding techniques to avoid vehicle
overturns on hills. Be sure that you can maneuver your ATV well on flat ground before attempting any incline and then practice riding first on
gentle slopes. Try more difficult climbs only after
you have developed your skill. In all cases avoid
inclines with slippery or loose surfaces, or obstacles that might cause you to lose control.
q
WARNING
POTENTIAL HAZARD
Operating on excessively steep hills.
WHAT CAN HAPPEN
The vehicle can overturn more easily on
extremely steep hills than on level surfaces or small hills.
HOW TO AVOID THE HAZARD
Never operate the ATV on hills too steep
for the ATV or for your abilities.
Practice on smaller hills before attempting
large hills.
It is important when climbing a hill to make sure
that your weight is transferred forward on the
ATV. This can be accomplished by leaning forward and, on steeper inclines, standing on the
footboards and leaning forward over the handlebars.

7-257-25
Page 79
If you are climbing a hill and you find that you
have not properly judged your ability to make it
to the top, you should turn the ATV around while
you still have forward motion (provided you have
the room to do so) and go down the hill.
q
WARNING
POTENTIAL HAZARD
Improperly crossing hills or turning on
hills.
WHAT CAN HAPPEN
Could cause loss of control or cause the
ATV to overturn.
HOW TO AVOID THE HAZARD
Never attempt to turn the ATV around on
any hill until you have mastered the turning technique as described in the Owner’s

RIDING DOWNHILL
When riding your ATV downhill, shift your weight
as far to the rear and uphill side of the ATV as
possible. Move back on the seat and sit with
your arms straight. Improper braking may cause
a loss of traction.
Use caution while descending a hill with loose or
slippery surfaces. Braking ability and traction
may be adversely affected by these surfaces.
Improper braking may also cause a loss of traction. Whenever possible, ride your ATV straight
downhill. Avoid sharp angles which could allow
the ATV to tip or roll over. Carefully choose your
path and ride no faster than you will be able to
react to obstacles which may appear.
q

CROSSING A SLOPE
Traversing a sloping surface on your ATV
requires you to properly position your weight to
maintain proper balance. Be sure that you have
learned the basic riding skills on flat ground
before attempting to cross a sloping surface.
Avoid slopes with slippery surfaces or rough terrain that may upset your balance.
As you travel across a slope, lean your body in
the uphill direction. It may be necessary to correct the steering when riding on loose surfaces
by pointing the front wheels slightly uphill. When
riding on slopes be sure not to make sharp turns
either up or down hill.
If your ATV does begin to tip over, gradually
steer in the downhill direction if there are no
obstacles in your path. As you regain proper balance, gradually steer again in the direction you
wish to travel.

Page 89
SLIDING AND SKIDDING
Care should be used when riding on loose or
slippery surfaces since the ATV may slide. If
unexpected and uncorrected, sliding could lead
to an accident.
To reduce the tendency for the front wheels to
slide in loose or slippery conditions, positioning
your weight over the front wheels will sometimes
help.
If the rear wheels of your ATV start to slide sideways, control can usually be regained (if there is
room to do so) by steering in the direction of the
slide. Applying the brakes or accelerating is not
recommended until you have corrected the
slide.
7-387-38
Page 90
With practice, over a period of time, skill at controlled sliding can be developed. The terrain
should be chosen carefully before attempting
such maneuvers, since both stability and control
are reduced. Bear in mind that sliding maneuvers should always be avoided on extremely
slippery surfaces such as ice, since all control
may be lost.
q
WARNING
POTENTIAL HAZARD
Skidding or sliding improperly.
WHAT CAN HAPPEN
You may lose control of this ATV. You
may also regain traction unexpectedly,
which may cause the ATV to overturn.
HOW TO AVOID THE HAZARD
Learn to safely control skidding or sliding
by practicing at low speeds and on level,
smooth terrain.
On extremely slippery surfaces, such as
ice, go slowly and be very cautious in
order to reduce the chance of skidding or
sliding out of control.

Steer in the direction of the slide if you have
the room.
Applying the brakes or accelerating is not recommended until you have corrected the slide.
(See pages 7-38–7-39.)
8 If your ATV doesn’t turn when you want it to:
Bring the ATV to a stop and practice the turning maneuvers again. Be sure you are putting
your weight on the footboard to the outside of
the turn. Position your weight over the front
wheels for better control. (See pages 7-22–
7-23.)
8 If your ATV begins to tip while turning:
Lean more into the turn to regain balance. If
necessary, gradually let off the throttle and/or
steer to the outside of the turn. (See pages
7-22–7-33.)
8 If your ATV can’t make it up a hill you are try-
ing to climb:
Turn the ATV around if you still have forward
speed. If not, stop, dismount on the uphill side
of the ATV and physically turn the ATV
around. If the ATV starts to slip backwards
DO NOT USE THE REAR BRAKE - the ATV
may tip over on top of you. Dismount the ATV
on the uphill side. (See pages 7-24–7-29.)
7-407-40
Page 92
8 If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned
towards the uphill side of the ATV to maintain
proper balance. If the ATV starts to tip, steer
down the hill (if there are no obstacles in your
way) to regain balance. If you discover that
the ATV is going to tip over, dismount on the
uphill side. (See pages 7-32–7-33.)
8 If your ATV encounters shallow water:
Ride slowly and carefully through slow moving water, watching for obstacles. Be sure to
let water drain from the ATV and CHECK
YOUR BRAKES FOR PROPER OPERATION
when you come out of the water. Do not continue to ride your ATV until you have regained
adequate braking ability. (See pages 7-34–
