Severe braking can
cause the rear wheel to
lift off the ground.
When braking, bear in
mind that the ABS control
cannot be relied on in all
circumstances to prevent the
rear wheel from lifting off the
ground.
What are the design
characteristics of the
BMW Motorrad ABS?
The BMW Motorrad ABS en-
sures driving stability on any
surface within the limits of
driving physics. The system
is not optimized for special
requirements resulting under
extreme weather conditions
offroad or on the racetrack.
Special situations
To detect the tendency of the
wheels to lock up, the speeds
of the front and rear wheel
are compared. If implausible
values are detected over a
longer period of time, the ABS
function is deactivated for
safety reasons and an ABS
fault is indicated. The condi-
tion for a fault message is the
completed self-diagnosis.
In addition to problems on the
BMW Motorrad ABS, unusual
driving conditions can also
lead to a fault message.
Unusual driving conditions:
Driving on the rear wheel
(wheely) for a longer period.
Rear wheel spinning in
place with front brake pulled
(burn out).
Heating up on the main or
auxiliary stand at idle or with
gear engaged.
Locked-up rear wheel for a
longer period of time, e.g.
when riding downhill of-
froad.
Should a fault message result
due to one of the driving con-
ditions described above, the
ABS function can be reacti-
vated by switching the ignition
off and then on again.
How important is regular
maintenance?
Any technical system is
always only as good as
its maintenance condition.
To ensure that the BMW Mo-
torrad Integral ABS is in an
optimally maintained condi-
tion, it is vital that the spec-
ified inspection intervals be
complied with.
