F01998-10
Info
In the Offroad ABS mode, the rear wheel may lock and
there is a risk of falling.
The curve dependent control is only active in ABS
mode Road.
The ABS operates with two independent brake circuits (front and
rear brakes). When the ABS control unit detects a locking ten-
dency in a wheel, ABS begins regulating the brake pressure. The
control function causes a slight pulsing of the hand and foot brake
levers.

The ABS warning 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 is lit while riding, this indicates a fault in the
ABS. 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 warning lamp may also light up if the rotating speeds of
the front and rear wheels differ greatly under extreme riding con-
ditions, for example when making "wheelies" or if the rear wheel
spins. This causes the ABS to switch off.
To reactivate the ABS, stop the vehicle and switch off the ignition.
The ABS is reactivated when the vehicle is switched on again. The
ABS warning lamp goes out after starting off.
