higher braking efficiency than
standard brake systems.
ABS anti-lock braking
system
ABS prevents the wheels
from locking during braking,
thus contributing significantly
to road safety.
Rear wheel lift
Even during severe braking,
a high level of tire 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 motor-
cycle can flip over.
Severe braking can
cause the rear wheel to
lift off the ground.
Bear in mind that ABS can-
not be relied on in all circum-
stances to prevent the rear
wheel from lifting clear of the
ground.
Residual braking func-
tion
With the ignition switched off,
during the self-diagnosis and
in the event of a fault in the
BMW Integral ABS, the brake
circuits concerned only have
the residual braking function.
The residual braking function
is the braking power with-
out the hydraulic servo as-
sistance of the BMW Integral
ABS. Under these circum-
stances, therefore, you must
apply considerably higher
pressure to the brake levers
in question in order to apply
the brakes, and lever travel
is longer. When the residu-
al braking function is active,
the ABS function is unavail-
able in the brake system in
question. When the residu-
al braking function is active,
the integral braking function
is partially or entirely unavail-
able.
Without the ABS func-
tion, the wheels could
lock during very hard brak-
ing. Without servo-assisted
brakes, considerably greater
force is required to brake.
The altered braking behavior
can lead to accidents.
Avoid hard braking whenev-
er possible. Brake early, as
increased braking force is re-
quired.
Have the malfunction correct-
ed as soon as possible by a
specialized workshop, prefer-
ably an authorized BMW Mo-
torrad retailer.
