13 BRAKE SYSTEM 102
13.1 Antilock Braking System (ABS)
402052-10
The ABS unit

, which consists of a hydraulic unit, ABS control unit, and return pump, is
installed under the seat. A wheel speed sensor

is located at the front and rear wheels.
Warning
Danger of accidents Changes to the vehicle impair the function of the ABS.
– Only allow the rear wheel to spin with the front brake applied if the ABS is
switched off (burn out).
– Do not make any changes to the suspension travel.
– Only use spare parts on the brake system which have been approved and recom-
mended by KTM.
– Only use tires/wheels approved by KTM with the corresponding speed index.
– Maintain the specified tire air pressure.
– Service work and repairs must be performed professionally. (Your authorized
KTM workshop will be glad to help.)
The ABS is a safety system that prevents locking of the wheels when driving straight ahead
without the influence of lateral forces.
Warning
Danger of accidents Vehicle rollover
– It is not always possible to prevent vehicle rollover in extreme riding situations
(e. g. luggage loaded with a high center of gravity, varying road surfaces, steep
descents, 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
