Rear wheel lift

Even under severe braking, a
high level of tyre grip can mean
102
that the front wheel does not
lock up until very late, if at all.
Consequently, ABS does not in-
tervene until very late, if at all.
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.
Severe braking can cause
the rear wheel to lift off the
ground.
When you brake, bear in mind
z
that ABS control cannot be relied
on in all circumstances to prevent
the rear wheel from lifting clear of
the ground.
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 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 Race ABS, ex-
ceptional riding conditions can
lead to a fault message being is-
sued.
Exceptional riding
conditions:
Heating up with the motorcycle
on an auxiliary stand, in neutral
or with a gear engaged.
Rear wheel locked by the en-
gine brake for a lengthy period,
for example while descending
steep gradients.
If a fault message is issued on
account of exceptional riding
conditions as outlined above, you
can reactivate the ABS function
by switching the ignition off and
on again.
What significance
devolves on regular
maintenance?
Invariably, a technical sys-
tem cannot perform beyond
the abilities dictated by its level
of maintenance.
In order to ensure that the BMW
Motorrad Race ABS is always
maintained in optimum condition,
it is essential for you to comply
strictly with the specified inspec-
tion intervals.
