ABS warning lamp – models with ABS (antilock brake system)
The ABS warning lamp [1] 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. The ABS is no longer active and the wheels can lock when braking.
NOTE:
The brake system will still function but ABS control will no longer be active. Continue to
drive carefully and have the ABS checked at an authorized KTM workshop.
NOTE:
The ABS warning lamp can also light up if there is a large deviation between the speed of
the front and rear wheel in extreme driving situations, e.g. during a wheelie or if the rear
wheel slips when accelerating on loose ground. The ABS will no longer be active and the
wheels can lock when braking. To activate the ABS again, stop and switch off the ignition.
If the warning lamp goes off again at a speed of approx. 5 KPH after you drive off, the ABS
is active and fully operative.
ABS button – models with ABS (antilock brake system)
The ABS button [2] switches off the ABS. To switch off the ABS, stop the motorcycle and
press the ABS button for at least 3 seconds with the engine running. Let go of the ABS but-
ton as soon as the ABS warning lamp starts blinking fast. The ABS warning lamp will blink
slowly to indicate that the ABS is switched off.
To switch the ABS on again, stop and switch off the ignition. The ABS will be active again
when you switch on the ignition.
