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
intervene until very late, if at all.
Under these circumstances
the rear wheel can lift off the
ground, and the outcome can
be a highsiding situation in
which the motorcycle can flip
over.
Severe braking can
cause the rear wheel to
lift off the ground.
Bear in mind that ABS cannot
be relied on in all circumstanc-
es to prevent the rear wheel
from lifting clear of the
ground.c
Residual braking function
When the ignition if off, while
self-diagnosis is in progress,
and if a fault develops in the
BMW Integral ABS, only a
residual braking function is
available in the brake circuits
in question. Residual braking
function is the braking per-
formance available without
hydraulic assistance. Under
these circumstances, there-
fore, you must apply consider-
ably higher pressure to the
brake levers in question in
order to apply the brakes, and
lever travel is longer. When the
residual braking function is
active, the ABS function is
unavailable in the brake sys-
tem in question. When the
residual braking function is
active, the integral braking
function is partially or entirely
unavailable.
Without the ABS func-
tion, the wheels may lock
under braking; without braking
power assistance, considera-
bly greater force is required to
brake.
Think well ahead and brake
carefully; avoid severe brak-
ing. Have the fault rectified as
soon as possible by a special-
ist workshop, preferably an
authorised BMW motorcycle
dealer.c
