RESIDUAL BRAKING
FUNCTION
If the BMW Integral ABS devel-
ops a fault, a RESIDUAL BRAK-
ING FUNCTION only is available
in the brake circuits in question.
The RESIDUAL BRAKING
FUNCTION is the braking effi-
ciency without the hydraulic
servo assistance of the BMW
Integral ABS.
Under these circumstances,
therefore, you must apply CON-
SIDERABLY 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 system in question.
When the RESIDUAL BRAKING
FUNCTION is active, the inte-
gral braking function is partially
or entirely unavailable.
d Warning:
When the RESIDUAL BRAK-
ING FUNCTION is active,
maintain a defensive riding
style and proceed immediate-
ly to the nearest specialist
workshop, preferably an au-
\f Note:
When the RESIDUAL BRAKING
FUNCTION is active at the front
wheel, it is advisable to set ad-
juster A of the front-brake lever
to position 4 (
b 27).
The RESIDUAL BRAKING
FUNCTION is active under the
following circumstances:
– Ignition off
– Before and during self-diag-
nosis (
b 72)
– Fault in the BMW
Integral ABS (
b 75)
\f Note:
When the RESIDUAL BRAKING
FUNCTION is active for both
brake circuits, the noise of the

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
motorcycle if the brakes are
applied too hard and the
w h ee ls l o ck o r th e r e ar w h ee l
lifts clear of the ground as a
result of a high level of tyre
adhesion. Have the defect
rectified immediately by a
specialist workshop, prefera-
bly an authorised
BMW motorcycle dealer.

Know how…In recent years, motorcycles ’
technical design features have
become more and more
sophisticated.
Motronic, electronic ignition,
integral brakes, the catalytic
converter or the use of four
valves per cylinder are clear
signs that far more than basic
technical knowledge may be
needed to solve certain prob-
lems. In addition, high-tech
materials are increasingly tak-
ing the place of conventional
ones, which again calls for thor-
ough and expert knowledge if
they are to be handled correctly
during repair work.
To be sure of achieving the nec-
essary standard, it is always
advisable to consult your
authorised BMW motorcycle
dealer. The authorised BMW motorcy-
cle dealer employs staff who
attends regular and compre-
hensive training courses.
Authorised BMW motorcycle
dealers also receive all the cur-
rent technical information and
are therefore fully aware of the
latest developments.
…
technical features …The authorised BMW motorcy-
cle dealer’s staff has the experi-
ence and all the necessary
facts at its disposal when it
comes to solving problems
quickly and effectively. Work-
shops are equipped with the
latest technical facilities, for
example the special tools
developed by BMW, such as
the BMW diagnostic system
and exhaust emissions tester.

Regular visits to the workshop
for routine servicing are
strongly recommended even
after the warranty period has
elapsed. They are the only way
to be genuinely certain that your
BMW motorcycle is being kept
in perfect working order.
For generous treatment of
claims submitted after the war-
ranty period has expired, evi-
dence of regular maintenance
by an authorised BMW motor-
cycle dealer is essential.
Certain signs of wear may not
otherwise be noticed until it is
too late to put them right at
moderate cost. The staff in the authorised BMW
motorcycle dealer
’s workshop
know every detail of your motor-
cycle and can take remedial
action if necessary before minor
faults develop into serious prob-
lems. By having the necessary
repairs done properly and in good
time, you save time and money in
the long run.
… serviceYou can obtain accurate advice
in all cases, and make appoint-
ments with a firm completion
deadline which we will comply
with punctually. But the most
gratifying feeling of all is that
your BMW is in genuinely good
shape when it leaves the author-
ised BMW motorcycle dealer ’s
workshop – and above all, safe.
