Braking
When possible, reduce your speed or complete braking before
entering a turn. Avoid braking or closing the throttle quickly while
turning. Either action may cause one or more wheels to slip and
reduce your control of your ATV.
Your ability to brake in a turn and to brake hard in an emergency
situation are important riding skills.
When descending a long, steep grade, use engine compression
braking by downshifting, with intermittent use of both brakes.
Continuous brake application can overheat the brakes and reduce
their effectiveness.
Riding with your foot resting on the brake pedal or your hands on
the brake levers may overheat the brakes, reducing effectiveness.
For information on how to apply the brakes in various riding
situations, see the following section, Riding Your ATV.
