12 BRAKE SYSTEM 88
12.1 ABS/antilock brake system
402028-10
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 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 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 riding 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.
