Turning

Handling characteristics for ATVs vary depending upon basic design

and how they are equipped. The turning information in this handbook

applies to most ATVs with one exception: ATVs with unlocked differen-

tials. If your ATV has a differential, be sure to lock the rear axle before

practicing the turning techniques in this handbook. Refer to your Yamaha

owner's manual for instructions.

ATVs with solid rear axles, and those with locked differentials, turn both

rear wheels at the same speed. This means when turning, the inside

wheel must "slip"

slightly on the sur-

face (see Figure 1).

ATVs with unlocked

differentials allow the

rear wheels to turn at

different speeds. If a

rear wheel on an ATV

with an unlocked dif-

ferential leaves the

ground, it will spin

freely. Then when it

touches the ground

again, it my grab and

some control.

Turning Basics

Always check your owner's manual for the recommended turning tech-

niques for your ATV. The following basic turning technique applies to

ATVs ridden at low to moderate speeds. Be sure to practice turning at low

speeds before attempting to turn at faster speeds. Do not turn at exces-

sive speed.

At Low Speeds

• Move your body

weight

forward

and to the inside of

the turn.

• Turn the handle-

bars while looking

in the direction of

the turn.

As you increase

speed or turn more

sharply, move your

body weight farther

toward the inside of

the turn to maintain

your balance.

If your ATV starts to tip while turning, lean your body farther into the

turn while gradually making the turn wider, if possible.

At Higher Speeds

The

method

turning at a higher

speed is similar to

turning

lower

speed. The difference

that

speed

increases you must

lean farther forward

toward the inside of

the turn. This is to

counteract the higher

centrifugal forces as

cornering

speed

increases.

If your ATV starts to tip toward the outside of the run while turning, lean

your upper body farther into the turn while gradually reducing throttle and

if possible, make the turn wider by straightening the handlebars. Keep

you feet on the footrests.

Sharp Turns

Learning to make sharper turns through practice will help you respond

to crooked trails or obstacles within your path.

Be sure to slow down before the turn. Keep your eyes up, looking

through the turn at your intended path of travel. Watch for terrain irregu-

larities so that you can slow down as necessary. Sharper turns require

more leaning in the direction of the turn. If an error in judgement causes

the ATV to start to tip toward the outside of the turn, straighten the han-

dlebars or lean your upper body more into the turn.

Remember it is important to first practice gradual turns and then

progress toward sharper turns as your riding skills develop. Be patient

and practice basic skills before moving on to more difficult manoeuvres.

Quicker Turns

Quicker

turns

are

sometimes required to

avoid obstacles in your

path. You should practice

coordinating speed, body

position and weight shift

to help you make quick

directional changes.

Keep your feet on the

footrests

maintain

maximum

control

for

manoeuvring the ATV.

Quicker turns require quicker weight shifts. It helps to rise off the seat

slightly (not standing up). Quicker turns are sometimes easier to negoti-

ate if you combine a short burst of throttle with the proper weight shift.

Look well ahead and allow the ATV to move underneath you. As with any

turn, if the ATV starts to tip toward the outside of the turn, slow down and

straighten the handlebars and/or lean more to the inside of the turn.

Adjust your speed to match conditions.
