Warning
Danger of accidents Impaired ABS function
–
The ABS cannot function properly if certain modifications have been made such
as shorter or longer suspension travel, other rim diameters, other tires, an incor-
rect tire air pressure, other brake linings, etc.
–
The ABS will only function correctly if the spare parts used in the brake system
and the tires have been approved and/or recommended by KTM.
–
Maintenance work and repairs must be carried out professionally. (Your autho-
rized KTM workshop will be glad to help.)
The ABS is a safety system that prevents locking of the wheels when the vehicle is traveling
straight ahead without the action of lateral forces.
The ABS operates with two independent brake circuits (front brake and rear brake). During
normal operation, the brake system operates like a conventional brake system without ABS.
If the ABS control unit detects a locking tendency in one of the wheels, the ABS system
begins intervening by controlling the brake pressure. The hand brake lever and foot brake
lever vibrate lightly when the ABS control function is active.
The ABS warning lamp
then goes out after starting off. If it does not go out after starting off, or if it lights up while
the vehicle is in motion, this indicates a fault in the ABS system. In this case, the ABS is
2 0 0 2 no longer active and the wheels may lock during full brake application. The brake system
itself remains functional but without the added ABS control.
The ABS warning lamp may also light up if the speeds of the front and rear wheels differ
from each other under extreme riding conditions, such as during wheelies or when the rear
wheel spins. This switches off the ABS.
To reactivate the ABS, stop the vehicle and switch off the ignition. ABS is reactivated when
401188-10
the vehicle is switched back on. The ABS warning lamp goes out after the vehicle starts off.
