cedure is essential if the tyres are

to achieve maximum grip.

Tyres do not have their full

grip when new and there

is a risk of accidents at extreme

angles of heel.

Avoid extreme angles of heel.

Brakes

How can stopping

distance be minimised?

Each time the brakes are applied,

a load distribution shift takes

place with the load shifting for-

ward from the rear to the front

wheel. The sharper the motor-

cycle decelerates, the more load

is shifted to the front wheel. The

higher the wheel load, the more

braking force can be transmitted

without the wheel locking.

To optimise stopping distance,

apply the front brakes rapidly and

keep on increasing the force you

apply to the brake lever. This

makes the best possible use

of the dynamic increase in load

at the front wheel. Remember

to pull the clutch at the same

time. In the "panic braking situ-

ations" that are trained so fre-

quently braking force is applied

as rapidly as possible and with

the rider's full force exerted on

the brake levers; under these cir-

cumstances the dynamic shift

in load distribution cannot keep

pace with the increase in de-

celeration and the tyres cannot

transmit the full braking force to

the surface of the road. ABS has

to intervene to keep the front

wheel from locking; this increases

stopping distance.

Descending mountain

passes

There is a danger of the

brakes fading if you use

only the rear brakes when des-

cending mountain passes. Under

extreme conditions, the brakes

could overheat and suffer severe

damage.

Use both front and rear brakes,

and make use of the engine's

braking effect as well.

Wet brakes

After the motorcycle has

been washed, ridden

through water or ridden in

the rain, the brake discs and

pads might be wet and the

brakes might not take effect

immediately.

Apply the brakes in good time

until the brakes have dried out.

Salt on brakes

The brakes may fail to take

effect immediately if the

motorcycle was ridden on salt-

covered roads and the brakes

were not applied for some time.

Apply the brakes in good time

until the salt layer on the brake
