Under these circumstances the
rear wheel can lift off the ground,
and the outcome can be a high-
siding situation in which the mo-
torcycle can flip over.
WARNING
Lifting off of the rear wheel
due to heavy braking.
Accident hazard
When braking heavily, bear in
mind that the ABS control can-
not always be relied on to pre-
vent the rear wheel from lifting
off the ground.
What are the design
characteristics of the
BMW Motorrad Integral
ABS?
The BMW Motorrad Integral ABS
ensures driving stability on any
surface 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 fault is indicated. The
condition for a fault code is the
completed self-diagnosis.
In addition to problems on the
BMW Motorrad Integral ABS,
unusual driving conditions can
also lead to a fault code.
Unusual driving conditions:
Heating up on the main or aux-
iliary stand at idle or with gear
engaged.
Rear wheel locked by the en-
gine brake for a lengthy period,
for example while descending
on a loose surface.
Should a fault code result due to
one of the driving conditions de-
scribed above, 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.
