Therefore, unless the wheel on the inside [ECB01071] Use this same procedure as you move into the of the turn is allowed to slip or lose some traction,...
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 move- ments, or too much speed for the sharpness of the turn may cause the ATV to tip.
Page 73
Shift your weight forward. Never open the throttle suddenly or make sudden gear changes. The ATV could flip over backwards. Never go over the top of any hill at high speed. An obstacle, a sharp drop, or another vehicle or person could be on the other side of the hill.
Page 74
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 footrests and leaning forward over the handlebars. Whenever possible, ride straight up hills.
Page 75
If you start to roll backwards, DO NOT apply the rear brake, and apply the front brake gradually. The ATV could easily tip over backwards. When fully stopped, apply the rear brake as well, and then lock the parking brake. Dismount the ATV im- mediately on the uphill side or to a side if pointed straight uphill.
RIDING DOWNHILL When riding your ATV downhill, shift your weight EWB01131 as far to the rear and uphill side of the ATV as pos- WARNING sible. Move back on the seat and sit with your arms Going down a hill improperly could cause straight.
Avoid crossing the side of a steep hill. 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 tech- nique as described in the Owner’s Manual on level ground.

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 footrest to the outside of the turn. Position your weight over the front wheels for better control.

If your ATV is traversing a sloping surface: Be sure to ride with your weight positioned to- wards 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.
