What is the design
baseline for
BMW Motorrad ABS?
Within the limits imposed by
physics, BMW Motorrad ABS en-
sures directional stability on any
surface. The system is not op-
timised for special requirements
that apply under extreme com-
petitive situations off-road or on
the track.
Special situations
The speeds of the front and rear
z
wheels are compared as one
means of detecting a wheel's
incipient tendency to lock. If
the system registers implaus-
ible values for a lengthy period
the ABS function is deactivated
for safety reasons and an ABS
fault message is issued. Self-dia-
gnosis has to complete before
fault messages can be issued.
In addition to problems with the
BMW Motorrad ABS, exceptional
riding conditions can lead to a
fault message being issued.
Exceptional riding
conditions:
Riding for a lengthy period with
the front wheel lifted off the
ground (wheelie).
Rear wheel rotating with the
vehicle held stationary by ap-
plying the front brake (burn-
out).
Heating up with the motorcycle
on the centre stand or an auxil-
iary stand, engine idling or with
a gear engaged.
Rear wheel locked for a lengthy
period, for example while des-
cending off-road.
If a fault message should
be triggered due to one of
the above-described driving
conditions, the ABS function can
be re-activated by switching the
ignition off and then on again.
What significance
devolves on regular
maintenance?
WARNING
Brake system not regularly
serviced.
Risk of accident
In order to ensure that the
BMW Motorrad ABS is always
maintained in optimum condi-
tion, it is essential for you to
comply strictly with the spe-
cified inspection intervals.
Reserves for safety
The potentially shorter braking
distances which BMW Motorrad
ABS permits must not be used
as an excuse for careless riding.
ABS is primarily a means of en-
