Off-road deactivation
In contrast to road riding, when
BMW Integral ABS should
always be active in order to pre-
vent wheel lock and a resulting
accident, it may be desirable to
dispense with ABS when riding
off-road or on a loose surface.
This is the reason why the ABS
function of BMW Integral ABS
can be deactivated.
Deactivating ABS
Never switch the ignition off
and on unless the motorcycle
is at a standstill.
Brake boost and the integral
function remain operational,
even if the ABS function is de-
activated.
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.
