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. There-
fore, 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.
WARNING
_ Always follow proper procedures for turning
as described in this Owner’s Manual.
Practice turning at low speeds before attempt-
ing to turn at faster speeds. Do not turn at
speeds too fast for your skills or the condi-
tions. _

2. Support your weight on the outer footboard.
1. Se pencher vers l’intérieur du virage.
2. S’appuyer sur le repose-pied extérieur.
1. Inclínese hacia el interior del giro.
2. Descanse su peso en el descansapie exterior.
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 direc-
tion) 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.
This procedure should be practiced at slow speed
many times in a large off-road area with no obsta-
cles. 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 proce-
dure 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.

If your ATV has stalled or stopped and you believe
you can continue up the hill, restart carefully to
make sure you do not lift the front wheels which
could cause you to lose control. If you are unable
to continue up the hill, dismount the ATV on the
uphill side. Physically turn the ATV around and
then descend the hill.
If you start to roll backwards, DO NOT apply either
brake abruptly. If you are in 2WD, apply only the
front brake. When this ATV is in 4WD, all wheels
(front and rear) are interconnected by the drive
train. This means that applying either the front
brake or the rear brake will brake all wheels. When
descending hills, using either brake lever or the
brake pedal will brake the wheels on the downhill
side. Avoid sudden application of either the front or
rear brake because the wheels on the uphill side
could come off the ground. The ATV could easily
tip over backwards. Apply both the front and rear
brakes gradually, or dismount the ATV immediate-
ly on the uphill side.

RIDING DOWNHILL
When riding your ATV downhill, shift your weight
as far to the rear and uphill side of the ATV as pos-
sible. Move back on the seat and sit with your
arms straight. Engine compression will do most of
the braking for you. For maximum engine com-
pression braking effect, change to 4WD before be-
ginning to descend the hill. 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.
When this ATV is in 4WD, all wheels (front and
rear) are interconnected by the drive train. This
means that applying either the front brake or the
rear brake will brake all wheels. When descending
hills, using either brake lever or the brake pedal
will brake the wheels on the downhill side. Avoid
sudden application of either the front or rear brake
because the wheels on the uphill side could come
off the ground. Apply both the front and rear
brakes gradually.

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 slip-
pery 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.

SLIDING AND SKIDDING
Care should be used when riding on loose or slip-
pery surfaces since the ATV may slide. If unex-
pected 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 side-
ways, 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.

WHAT TO DO IF ...
This section is designed to be a reference guide
only. Be sure to read each section on riding tech-
niques 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 pages 7-39–7-43.)


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 7-39–7-43.)


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 rec-
ommended until you have corrected the slide.
(See pages 7-71–7-73.)

Front brake pad check
Check the brake pads for damage and wear. If a
brake pad thickness is less than 1 mm, have a
Yamaha dealer replace the pads as a set.NOTE:_ The wheels need to be removed to check the
brake pads. (See pages 8-93–8-95 for removal
and installation procedures.) _
EBU00313
Rear brake shoe inspection
A wear indicator is provided on the rear brake.
This indicator allows checking of brake shoe wear
without disassembling the brake. Apply the rear
brake and check the position of the indicator. If the
indicator reaches the wear limit line, ask a
Yamaha dealer to replace shoes as a set.
