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 traveling straight
ahead without the action of lateral forces.
ABS works with two mutually independent brake circuits (front and rear brake). Under nor-
mal conditions, the brake system works like a conventional brake without ABS. When the
ABS control unit detects the tendency of a wheel to lock, ABS begins controlling the brak-
ing pressure. The control process causes a light pulsation in the brake lever.
The ABS warning lamp

must light up after the ignition is switched on and go out after
you start riding. If it does not go out after you start riding or lights up during the trip, this
indicates an error in the ABS system. In this case, the ABS is no longer active and the
wheels may lock during braking. The brake system itself remains functional; only the ABS
control system is not operational.
The ABS warning lamp can light up if the rotational speeds of the front and rear wheels dif-
fer greatly in extreme riding situations, e.g. during wheelies or when the rear wheel spins.
This switches off ABS.
