Info
In the Offroad ABS mode, the rear wheel may lock and
there is a risk of falling.
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 reg-
ulating 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 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 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.
