apted to actual driving skills
and the road conditions.
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.
Reserves for safety
The potentially shorter braking
distances which ABS permits
must not be used as an ex-
cuse for careless riding. ABS
is primarily a means of ensur-
ing a safety margin in genuine
emergencies.
WARNING
Braking when cornering
Risk of accident despite ABS
Invariably, the rider bears
responsibility for assessing
road and traffic conditions
and adopting his or her style
of riding accordingly.
Do not take risks that would
negate the additional margin
of safety offered by this sys-
tem.
