Brake system - with BMW Integral ABSOE
Off-road deactivationIn contrast to road riding, where
BMW Integral ABS can always
prevent wheel locking and the
resulting accident, it may be
desirable for the rider to be able
to lock a wheel or prevent it
from rotating on rough terrain or
loose surfaces. This is the rea-
son why the BMW Integral ABS
enables you to deactivate the
ABS function temporarily.
OEOptional extra
Deactivating the ABS
d Warning:
Never switch the ignition off
or on unless the motorcycle is
at a standstill.
Brake boost and the integral
function remain operational,
even if the ABS function is de-
activated.
L Note:
The ABS function is reactivated
once the self-diagnosis routine
has completed successfully af-
ter you switch off the ignition
and switch it on again with the
motorcycle at a standstill.

If the ABS function is off – as
indicated by ABS warning

lock braking system are not

There is a risk of dropping the
motorcycle if the brakes are
applied too hard and the front
wheel locks or the rear wheel
lifts clear of the ground as a
result of a high level of front
tyre adhesion.
