Brake system - with BMW Integral ABSOE
Sensitive electronic
control
It takes skill and sensitive con-
trol of the brakes to pull up
safely on a motorcycle. If the
front wheel brake locks and the
wheel skids, the necessary lon-
gitudinal and lateral stabilising
forces are lost, and a fall can
result.
For this reason, the rider sel-
dom makes full use of available
braking performance in an
emergency.
OEOptional extra
BMW Integral ABS is the latest-
generation BMW ABS develop-
ment: by preventing both
wheels from locking and opti-
mising braking-force distribu-
tion by means of the integral
function, it offers much
improved braking performance
(
b 82). Full use is made of tech-
nical braking capacity to mini-
mise braking distances, even
when road conditions are poor.
When the motorcycle is ridden
in a straight line, the BMW Inte-
gral ABS is able to handle
emergency braking safely.

Brake system - with BMW Integral ABSOE
Partially integral brakesThe integral brake function
interlinks the front and rear
brakes, so both wheels are
braked when you operate the
brake lever.
The electronic controller in the
BMW Integral ABS computes
the braking-force distribution
between front and rear wheels,
and applies the brakes
accordingly.
Braking-force distribution
depends on load and is recal-
culated every time the ABS
controller comes into action.
In this partially integral brake
configuration, the integral brak-
ing function is activated only
when you pull the handbrake
lever. The footbrake lever acts
only on the rear brake.
Brake servoThe hydraulic pump in the BMW
Integral ABS actively boosts the
braking force acting on the
wheel when the brakes are
applied.
By boosting the braking force in
this way, the BMW Integral ABS
achieves higher braking effi-
ciency than standard brake
systems.
ABS
anti-lock brake system
ABS prevents the wheels lock-
ing under heavy braking, thus
contributing significantly to
road safety.

Off-road deactivationIn contrast to road riding, where
BMW Integral ABS can always
prevent wheel locking and the
resulting accident, it may be
desirable for the rider to be able
to lock a wheel or prevent it
from rotating on rough terrain or
loose surfaces. This is the rea-
son why the BMW Integral ABS
enables you to deactivate the
ABS function temporarily.

Deactivating the ABS
d Warning:
Never switch the ignition off
or on unless the motorcycle is
at a standstill.
Brake boost and the integral
function remain operational,
even if the ABS function is de-
activated.
L Note:
The ABS function is reactivated
once the self-diagnosis routine
has completed successfully af-
ter you switch off the ignition
and switch it on again with the
motorcycle at a standstill.

d Warning:
If the ABS function is off – as
indicated by ABS warning
light 1 – the safety reserves
afforded by the anti-
lock braking system are not
available until the
ABS function is reactivated.
There is a risk of dropping the
motorcycle if the brakes are
applied too hard and the front
wheel locks or the rear wheel
lifts clear of the ground as a
result of a high level of front
tyre adhesion.

d Warning:
If the BMW Integral ABS fails
in both brake circuits, a
RESIDUAL BRAKING FUNC-
TION only is available! (b 83)
d Warning:
When RESIDUAL BRAKING
FUNCTION (
b 83) is active,
maintain a defensive riding
style and proceed immediate-
ly to a specialist workshop,
preferably an authorised
BMW motorcycle dealer.
d Warning:
If there is a fault in the ABS
system, the reserves of safety
normally afforded by ABS are
not available until the defect
has been put right.
There is a risk of dropping the
machine if the brakes are ap-
plied too hard and the front
wheel locks or the rear wheel
lifts clear of the ground as a
result of a high level of front
tyre adhesion. Have the de-
fect rectified immediately by
a specialist workshop, prefer-
ably an authorised
BMW motorcycle dealer.
