ABS (ANTILOCK BRAKE SYSTEM) 990 ADVENTURE:
The ABS is a safety system that prevents the wheels from locking when driving straight ahead
without the influence of lateral forces. The ABS unit
[1]
, consisting of a hydraulic unit, an
electronic control unit and the electric pump motor, is located under the seat. Sensors
[2]
on the front and rear wheel send pulses to the control unit to indicate how fast the wheel is
turning.
The KTM 990 Adventure ABS operates with two independent brake circuits (front and rear
wheel brake). During normal service the brake system works just like a conventional brake
without the ABS. The ABS control phase sets in when the control unit detects that one of
the wheels is starting to lock. It releases the pressure in the respective brake circuit and
prevents the wheel from locking. You can feel the control function as a slight pulsing in the
brake lever.
The ABS warning lamp
[3]
must light up when the ignition is switched on and go out at a
speed of approx. 5 KPH after you drive off. If it stays on or lights up while driving, the ABS
is defective (see Troubleshooting).
The ABS can be switched off with the ABS button
[4]
(see Driving Instructions).
– Do not mount wheels with a different rim diameter. The ABS function can no longer be
guaranteed.
– Do not carry out any chassis modifications that extend or shorten the spring travel oth-
erwise the proper functioning of the ABS cannot be warranted.
– The ABS is designed to be used with the tires authorized by KTM and works best with
these tires. The ABS function cannot be guaranteed if other tires are used.
– Maximum ABS control can no longer be guaranteed if the tire pressure is incorrect.
