13 BRAKE SYSTEM
105
Warning
Danger of accidents Driving aids can only prevent a rollover within the physical limi-
tations.
It is not always possible to compensate for extreme riding situations, for exam-
ple with luggage loaded with a high center of gravity, varying road surfaces, steep
descents or full braking without disengaging the gear.
–
Adapt your riding style to the road conditions and your driving ability.
The ABS operates with two independent brake circuits (front and rear brakes). During nor-
mal operation, the brake system operates like a conventional brake system without ABS.
When the ABS control unit detects a locking tendency in a wheel, ABS begins regulating
the brake pressure. The regulating process causes a slight pulsing of the hand and foot
brake levers.
The ABS indicator lamp
3 must light up after the ignition is switched on and go out after
starting off. If it does not go out after starting off or if it lights up while riding, this indi-
cates a fault in the ABS system. In this case, the ABS is no longer enabled and the wheels
may lock during braking. The brake system itself stays functional; only ABS control is not
available.
The ABS indicator lamp may also light up if the rotating speeds of the front and rear wheels
differ greatly under extreme riding conditions, for example when making "wheelies" or if the
rear wheel spins. This causes the ABS to switch off.
To reactivate the ABS, the vehicle must be stopped and the ignition switched off. The ABS
is reactivated when the vehicle is switched on again. The ABS indicator lamp goes out
when you start off.
13.2 Checking the brake discs
Warning
Danger of accidents Worn-out brake discs reduce the braking effect.
–
Make sure that worn-out brake discs are replaced immediately. (Your authorized KTM workshop will be glad to help.)
