The ABS unit

, which consists of a hydraulic unit, ABS control unit, and return pump, is
installed under the seat. The front and rear wheels each have a wheel speed sensor

.
Warning
Danger of accidents Functional limitations of the ABS
–
The rear wheel may only be spun with the front brake applied (burn out) if the
ABS is switched off.
–
If the vehicle has been modified, such as shortened or lengthened spring deflec-
tions, different rim diameters, different tires, the wrong tire air pressure, differ-
ent brake linings, etc., the ABS will not function optimally. Optimal function-
ing of the ABS is only ensured if the brake system only contains spare parts and
tires that have been approved and/or recommended by KTM.
–
Service work and repairs must be performed properly. (Your authorized KTM
workshop will be glad to help.)
The ABS is a safety system that prevents locking of the wheels when the vehicle is traveling
straight ahead without the action of lateral forces.
Warning
Danger of accidents Rolling over of the vehicle
–
It is not always possible to prevent rolling over of the vehicle in extreme riding
situations (e. g. luggage loaded with a high center of gravity, varying road sur-
faces, steep descents, full braking without disengaging the gear). Adapt your
riding style to the road conditions and your riding ability.
The ABS operates with two independent brake circuits (front brake and rear brake). During
normal operation, the brake system operates like a conventional brake system without ABS.
If the ABS control unit detects a locking tendency in one of the wheels, the ABS system
begins intervening by controlling the brake pressure. The hand brake lever and foot brake
lever vibrate lightly when the ABS control function is active.
