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 63 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 64 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 65 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.
