What are the design
characteristics of the
BMW Motorrad ABS?
The BMW Motorrad ABS en-
sures riding stability on any sur-
face within the limits of riding
physics.
From a speed greater
than 2.5 mph (4 km/h), the
BMW Motorrad ABS can
ensure riding stability on any
surface within the limits of riding
physics. At lower speeds, the
BMW Motorrad ABS cannot
provide optimal support on
all surfaces due to system
limitations.
The system is not optimized for
the special conditions encoun-
tered under the extreme condi-
tions of competitive off-road and
race-track use.
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.
Apart from problems with the
BMW Motorrad ABS, unusual
riding conditions can also cause
a fault message to be generated:
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
Brake system not regularly
serviced
Accident hazard
To ensure that the
BMW Motorrad ABS is in a
properly maintained condition,
it is vital that the specified
service intervals are kept to.
