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:
●
Read this manual and all labels carefully and follow the operating procedures described.
●
Never operate an ATV without proper training or
instruction.

ATV without adult supervision, and never allow
continued use of an ATV by a child if he or she
does not have the abilities to operate it safely.
●
Never carry a passenger on an ATV.
●
Always avoid operating an ATV on any paved
surfaces, including sidewalks, driveways, parking lots and streets.
●
Never operate an ATV on any public street, road
or highway, even a dirt or gravel one.
●
Never operate an ATV without wearing an approved motorcycle helmet that fits properly. You

shield), gloves, boots, a long-sleeved shirt or a
jacket, and long pants.
●
Never consume alcohol or drugs before or while
operating this ATV.
●
Never operate at speeds too fast for your skills
or the riding conditions. Always go at a speed
that is proper for the terrain, visibility, operating
conditions, and your experience.

eration.
●
Always go slowly and be extra careful when op-
5
erating on unfamiliar terrain. Always be alert to
changing terrain conditions when operating the
6
ATV.
●
Never operate on excessively rough, slippery or
7
loose terrain until you have learned and practiced the skills necessary to control the ATV on
8
such terrain. Always be especially cautious on
9
these kinds of terrain.
●
Always follow proper procedures for turning as
described in this manual. Practice turning at low
speeds before attempting to turn at faster
speeds and never turn at excessive speeds.
●
Never operate the ATV on hills too steep for the
ATV or for your abilities. Practice on smaller hills
before attempting larger hills.
●
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 or make sudden gear changes.
Never go over the top of a hill at high speed.
●
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.
●
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.
●
Always use proper procedures if you stall or roll
backwards when climbing a hill. To avoid stalling, use the proper gear and maintain a steady
speed when climbing a hill. If you stall or roll
1-2
Page 11
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.
●
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.
●
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.
●
Never operate an ATV in fast flowing water or in
water deeper than that recommended in this
manual. 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.
●
Always use the size and type of tires specified in
this manual.
●
Always maintain proper tire pressure as described in this manual.
●
Never modify an ATV through improper installation or use of accessories.
●
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 or
pulling a trailer. Allow greater distance for braking.

Once the engine is running, movement of the throttle lever will increase the engine speed.
Regulate the speed of the ATV by varying the
throttle position. Because the throttle is springloaded, the ATV will decelerate, and the engine will
return to an idle any time the hand is removed from
the throttle lever.

CAUTION:
Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
Your Yamaha engine has been designed to use
regular unleaded gasoline with a pump octane
number [(R+M)/2] of 86 or higher, or a 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 the ethanol content does not exceed 10%. Gasohol containing
methanol is not recommended by Yamaha because it can cause damage to the fuel system or
ATV performance problems.

Page 29
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 to
heat from the engine or the sun.
HOW TO AVOID THE HAZARD
Do not overfill the fuel tank. Be careful not to
spill fuel, especially on the engine or exhaust
pipe. Wipe up any spilled fuel immediately.
Be sure the fuel tank cap is closed securely.
Do not refuel right after the engine has been
running and is still very hot.

hours of riding. For this reason, you should read
the following material carefully.
Since the engine is brand new, do not put an excessive load on it for the first 320 km (200 mi) or 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 that might result in engine overheating must be avoided.

Accessories and loading
EBU20920
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.
●
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 nonYamaha accessories, nor control over their quality or suitability. Choose a genuine Yamaha accessory, or one that is equivalent in design and
quality.
●
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.
●
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

EBU20930
Loading
As originally equipped, this ATV is not designed to
4
carry cargo or tow a trailer. If you choose to add ac-
5
cessories so that you can carry cargo or tow a trailer, you must use common sense and good
6
judgment as the stability and handling of an ATV
can be changed. When adding accessories, keep
7
the following points in mind:
●
Never exceed the weight limits shown. An over-
8
loaded ATV can be unstable.
9
MAXIMUM LOADING LIMIT
10
11
ATV loading limit (total weight of rider, cargo,
accessories, and tongue):
100.0 kg (220 lb)
●
If you are carrying cargo and towing a trailer, include the tongue weight in the maximum ATV
load limit.
●
Load cargo on the carriers as close to the center
of the ATV as possible. Put cargo at the rear of
the front carrier, at the front of the rear carrier,
and center it.
●
Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around. A
shifting load can cause an accident.
●
Make sure the load does not interfere with controls or your ability to see where you are going.
●
Ride more slowly than you would without a load.
The more weight you carry, the slower you
should go. Although conditions vary, it is good
practice not to exceed 2nd gear whenever you
are carrying heavier loads or when towing a trailer.
●
Allow more braking distance. A heavier ATV
takes longer to stop.
●
Avoid making sharp turns unless at very slow
speeds.
●
Avoid hills and rough terrain. Choose terrain
carefully. Added weight affects the stability and
handling of the ATV.

Do not ride in areas posted “no trespassing”.
Do not ride on private property without getting permission.
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. As you
get on the ATV, be sure not to accidentally move
the shift pedal. 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, pull the clutch lever to disengage the clutch and shift into 1st gear, and then
release the parking brake. Open the throttle gradually, and at the same time, release the clutch lever slowly. Once the ATV has attained adequate
speed, release the throttle lever and at the same
time, quickly pull in the clutch lever and shift into
2nd gear. Open the throttle part way and gradually
release the clutch. Use this same procedure as
you move into the higher gears. Be sure to coordinate the use of the throttle and shift pedal properly.
If the throttle is applied too abruptly or if the throttle
is not released during shifting, or if the shift pedal
is not released before applying the throttle, 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 throt-
10
tle and apply the brakes smoothly and evenly. As
you slow down, shift to a lower gear. Be sure that
11
the engine has sufficiently slowed before engaging
a lower gear. Improper use of the brakes or shifting
can cause the tires to lose traction, reducing control and increasing the possibility of an accident.
EWB01070
WARNING
POTENTIAL HAZARD
Engaging a lower gear when the engine
speed is too high.
WHAT CAN HAPPEN
The wheels could stop rotating. This could
cause loss of control, an accident and injury.
It could also cause engine or drive train damage.
HOW TO AVOID THE HAZARD
Make sure the engine has sufficiently slowed
before shifting to a lower gear.
TURNING YOUR ATV
To achieve maximum traction while riding off-road,
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.
7-17
Page 69
EWB01220
WARNING
POTENTIAL HAZARD
Turning improperly.
WHAT CAN HAPPEN
The 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.
1
2
1. Lean towards inside of turn.
2. Support your weight on the outer footrest.
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
1
changes, excessive braking, incorrect body movements, or too much speed for the sharpness of the
2
turn may cause the ATV to tip. If the ATV begins to
tip over to the outside while negotiating a turn, lean
3
more to the inside. It may also be necessary to
gradually let off on the throttle and steer to the out-
4
side of the turn to avoid tipping over.
Remember: Avoid higher speeds until you are
5
thoroughly familiar with the operation of your ATV.

CLIMBING UPHILL
Use proper riding techniques to avoid ATV over-
7
turns on hills. Be sure that you can maneuver your
ATV well on flat ground before attempting any in-
8
cline and then practice riding first on gentle slopes.
Try more difficult climbs only after you have devel-
9
oped your skill. In all cases avoid inclines with slip-
10
pery or loose surfaces, or obstacles that might
cause you to lose control.
EWB01090

Operating on excessively steep hills.
WHAT CAN HAPPEN
The ATV 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.

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.

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,
5
go slowly and be very cautious in order to reduce the chance of skidding or sliding out of
6
control.
7
With practice, over a period of time, skill at controlled sliding can be developed. The terrain
8
should be chosen carefully before attempting such
maneuvers, since both stability and control are re-
9
duced. Bear in mind that sliding maneuvers should
10
always be avoided on extremely slippery surfaces
such as ice, since all control may be lost.

WARNING
POTENTIAL HAZARD
Skidding or sliding improperly.
WHAT TO DO IF...
This section is designed to be a reference guide
only. Be sure to read each section on riding techniques completely.
WHAT TO DO...
●
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 page 7-17.)
●
If your ATV begins to tip while turning:
7-29
Page 81
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 page 7-17.)
●
If your ATV starts to slide sideways:
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 page 7-28.)
●
If your ATV can’t make it up a hill you are trying
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 page 7-19.)
●
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 page 7-19.)
●
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 page 7-25.)

chart.
To check the engine oil level
1. Place the ATV on a level surface.
2. Check the engine oil level on a cold engine.
NOTE:
If the engine was started before checking the oil
level, be sure to warm up the engine sufficiently,
and then wait at least ten minutes until the oil settles for an accurate reading.
3. Remove the engine oil filler cap, and then
wipe the dipstick off with a clean rag.
4. Insert the dipstick into the filler hole (without
screwing it in), and then remove it again to
check the oil level.
