CAUTION:
Do not shift gears without releasing the throt-
tle. Damage to the engine or drive train may
occur.
When slowing down or stopping, release the
throttle and apply the brakes smoothly and
evenly. As you slow down, shift to a lower
gear. Be sure that the engine has sufficiently
slowed before engaging a lower gear. Improp-
er use of the brakes or shifting can cause the
tires to lose traction, reducing control and in-
creasing the possibility of an accident.
WARNING
Make sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a
lower gear when the engine speed is too high
could cause the wheels to stop rotating.

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 in-
side 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 es-
sential 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.

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, al-
lowing 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 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 sur-
face 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.
1. Lean towards inside of turn.
2. Support your weight on the outer footrest.
1. Se pencher vers l’intérieur du virage.
2. Faire reposer son poids sur le repose-pied extérieur.
1. Inclínese hacia el interior del giro.
2. Descanse su peso en el descansapie externo.

If your ATV has stalled or stopped and you be-
lieve you can continue up the hill, restart care-
fully 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, dis-
mount the ATV on the uphill side. Physically
turn the ATV around and then descend the hill.
If you start to roll backwards, DO NOT use the
rear brake to stop or try to put the ATV in gear.
The ATV could easily tip over backwards. In-
stead, dismount the ATV immediately on the
uphill side.

CROSSING A SLOPE
Traversing a sloping surface on your ATV re-
quires 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 cor-
rect 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
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, position-
ing 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 direc-
tion of the slide. Applying the brakes or accel-
erating 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 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 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
recommended until you have corrected the
slide. (See pages 7-69 ~ 7-71.)
