the case when the brake pedal is
depressed either before or at the
same time as the brake lever is
pulled.
Rear wheel lift
Even under severe braking, a
high level of tyre grip can mean
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.
WARNING
Rear wheel lift due to severe
braking.
Risk of falling
When you brake sharply, bear
in mind that ABS control can-
not always be relied on to pre-
vent the rear wheel from lifting
clear of the ground.
What is the design
baseline for
BMW Motorrad Integral
ABS?
Within the limits imposed by
physics, the BMW Motorrad In-
tegral ABS ensures directional
stability on any surface. The sys-
tem is not optimised for special
requirements that apply under
extreme competitive situations
off-road or on the track.
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 Integral ABS,
exceptional riding conditions can
lead to a fault message being
issued.
Exceptional riding
conditions:
Heating up with the motorcycle
on the centre stand or an auxil-
iary stand, engine idling or with
a gear engaged.
Rear wheel locked by the en-
gine brake for a lengthy period,
for example while descending
on a loose surface.
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.
