What are the design
characteristics of the
BMW Motorrad ABS?
The BMW Motorrad ABS en-
sures driving stability on any sur-
face within the limits of driving
physics. The system is not op-
timized for special requirements
resulting under extreme weather
conditions offroad or on the race-
track.
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 de-
activated for safety reasons and
an ABS error is indicated. A self-
diagnosis routine must be com-
pleted before the error will be
displayed.
Unusual driving conditions can
lead to a fault code as well:
Driving on the rear wheel
(wheelie) for a longer period.
Rear wheel spinning in place
with front brake engaged (burn
out).
Warm-up on the center or aux-
iliary stand at idle or with gear
engaged.
Locked-up rear wheel for a
longer period of time, e.g.
when riding downhill offroad.
Should a fault code occur due to
an unusual driving condition, the
ABS function can be reactivated
by switching the ignition off and
then on again.
How important is regular
maintenance?
WARNING
Failure to have maintenance
performed on the brake sys-
tem regularly.
Accident hazard
To ensure that the ABS is in
a properly maintained condi-
tion, it is vital that the specified
service intervals be observed.
Reserves for safety
But remember: the potentially
shorter braking distances which
BMW Motorrad ABS permits
must not be used as an excuse
for careless riding. ABS is pri-
marily a means of ensuring a
safety margin in genuine emer-
gencies.
WARNING
Braking in curves.
Accident hazard despite ABS.
The rider is always responsi-
ble for adapting his/her driving
style.
Do not reduce the additional
safety function with careless
riding or unnecessary risks.
