Warning
Danger of accidents Driving aids can only prevent a
rollover within the physical limitations.
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 regu-
lating the brake pressure. The regulating process causes a slight
pulsing of the hand and foot brake levers.
The ABS indicator lamp

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 fault in
the ABS system. 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 indicator lamp may also light up if the rotating speeds of
the front and rear wheels differ greatly under extreme riding con-
