13 BRAKE SYSTEM
66
13.1 Anti-lock braking system (ABS)
H01908-10
The ABS module
1
, which consists of a hydraulic unit, ABS con-
trol unit, and return pump, is installed under the fuel tank. One
wheel speed sensor
2
is located in each case on the front and
the rear wheel.
Warning
Danger of accidents Changes to the vehicle impair the
function of the ABS.
–
Do not make any changes to the suspension travel.
–
Only use spare parts on the brake system which have
been approved and recommended by KTM.
–
Only use tires/wheels approved by KTM with the corre-
sponding speed index.
–
Maintain the specified tire pressure.
–
Ensure that service work and repairs are 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 Driving aids can reduce the probabil-
ity of a fall only within physical limits.
It is not always possible to compensate for extreme riding
situations, for example 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 normal operation, the brake system operates
like a conventional brake system without ABS. When the ABS con-
trol unit detects a locking tendency in a wheel, ABS begins reg-
ulating the brake pressure. The control function causes a slight
pulsing of the hand and foot brake levers.
The ABS warning 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 indicates a
malfunction in the ABS. 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 warning lamp may also light up if the rotating speeds of
the front and rear wheels differ greatly under extreme riding con-
ditions, for example when making "wheelies" or if the rear wheel
spins. This causes the ABS to switch off.
To reactivate the ABS, stop the vehicle and switch off the ignition.
The ABS is reactivated when the vehicle is switched on again. The
ABS warning lamp goes out after starting off.
