What is the design baseline
for BMW Motorrad Integral
ABS Pro?
Within the limits imposed by
physics, BMW Motorrad Integ-
ral ABS Pro ensures directional
stability on any surface. The
system is not optimised for
special requirements that ap-
ply under extreme competitive
conditions off-road or on the
track. The driving behaviour
should be adapted to actual
driving skills and the road con-
ditions.
Special situations
The speeds of the front and
rear wheels are compared
as one means of detecting a
wheel's incipient tendency to
lock. If the system registers
implausible values for a lengthy
period the ABS function is
deactivated for safety reasons
and an ABS fault message
is issued. Self-diagnosis has
to complete before fault
messages can be issued.
In addition to problems with
the BMW Motorrad ABS, ex-
ceptional riding conditions can
also cause a fault message to
be issued:
Heating up with the motor-
cycle on the centre stand or
an auxiliary stand, engine id-
ling or with a gear engaged.
Rear wheel locked by the
engine brake for a lengthy
period, for example while des-
cending on a loose or slippery
surface.
If a fault message is issued on
account of exceptional riding
conditions, you can reactivate
the ABS function by switching
the ignition off and on again.
What significance devolves on
regular maintenance?
WARNING
Brake system not regularly
serviced.
Risk of accident
In order to ensure that the
ABS is always maintained
in optimum condition, it is
essential for you to comply
strictly with the specified
inspection intervals.
Safety reserves
The potentially shorter
braking distances which
BMW Motorrad Integral
ABS Pro permits must not
be used as an excuse for
careless riding. The system is
