Safety marginBut remember: the potentially
shorter braking distances
which BMW Integral ABS per-
mits must not be used as an
excuse for careless riding. ABS
is primarily a means of ensuring
a safety margin in genuine
emergencies.
– You have to familiarise your-self with the new, electroni-
cally assisted braking. Try the
brakes several times when
you take your motorcycle out
for the first time. Find out for
yourself how the brakes feel.
– Never ride without due care
and attention, or assume that
good fortune will protect you
from your own foolhardiness
– Keep within the permitted
speed limits – Take care when cornering.
When you apply the brakes on
a corner, the motorcycle's
weight and momentum take
over and even BMW Integral
ABS is unable to counteract
their effects.

Brake system - with BMW Integral ABS*
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 accord-
ingly.
The baking-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 a higher braking
efficiency than standard brake
systems.
ABS - anti-lock brake
system*
ABS prevents the wheels lock-
ing under heavy braking when
the motorcycle is travelling in a
straight line, thus contributing
significantly to road safety.

RESIDUAL BRAKING
FUNCTION
If the BMW Integral ABS* develops
a fault, a RESIDUAL BRAKING
FUNCTION only is available in the
brake circuits in question.
The RESIDUAL BRAKING
FUNCTION is the braking efficiency
without the hydraulic servo assist-
ance of the BMW Integral ABS*.
Under these circumstances, there-
fore, 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 RESIDUAL BRAKING
FUNCTION is active, the ABS func-
tion 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.
d Warning:
When the RESIDUAL BRAKING
FUNCTION is active, maintain a
defensive riding style and pro-
ceed immediately to the nearest
specialist workshop, preferably
an authorised BMW motorcycle
dealer.
L Note:
When the RESIDUAL BRAKING
FUNCTION is active, it is advisable
to set adjuster A (
b 27) on the front-
brake lever to position 4.
The RESIDUAL BRAKING
FUNCTION is active under the fol- lowing circumstances:
– Ignition off
– Before and during self-diagnosis
(
b 72)
– Fault in the BMW Integral ABS* (
b 75)
L Note:
When the RESIDUAL BRAKING
FUNCTION is active for both brake
circuits, the noise of the pump is no
longer audible when you operate
the brake levers.

Always switch on the ignition

released.
Self-diagnosis cannot be per-

When self-diagnosis com-

d Warning:
If the BMW Integral ABS fails
in both brake circuits, a RESI-
DUAL BRAKING FUNCTION
only is available. (b 71)
d Warning:
If the RESIDUAL BRAKING
FUNCTION is active (
b 71),
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
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.

Check the motorcycle as follows:
– Ignition OFF: is brake pressure OK at
the brake levers?
– Are the brakes acting on both wheels?
– Is the brake system leaktight, no signs of brake fluid escaping?
The brake system is defective if the test
outcome is negative.

any doubts about the safety of the

Arrive safely
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 is 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
necessary standard, it is always
advisable to consult your
authorised BMW motorcycle
dealer.The authorised BMW motor-
cycle dealer employs staff that
attends regular and compre-
hensive training courses.
Authorised BMW motorcycle
dealers also receive all the
current technical information
and are therefore fully aware of
the latest developments.
… technical features …The authorised BMW motor-
cycle dealer's staff has the
experience and all the neces-
sary 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
MoDiTeC or exhaust
emissions tester.

Arrive safely
Training means extra safety
Cornering and braking
need to be practiced
Develop a “sixth sense” for
potentially dangerous situa-
tions. What this means: look
ahead, plan how to avoid possi-
bly dangerous situations and
study other road users' behav-
iour with a degree of healthy
scepticism.
– take bends smoothly and rhythmically, avoiding violent
braking and acceleration
– approach bends slower than
you feel they can be taken; a
neat riding style will get you to
your destination more safely
than sheer speed
– ride at the inner edge of the
ideal line, look ahead and plan
to leave the bend as smoothly
as you entered it Allow for reaction time when
judging braking distances.
– at a speed of 50 km/h
(31 mph), for instance,
one second's hesitation
means that about 14 metres
(46 feet) are covered addition-
ally before the brakes are
applied
– at 90 km/h (56 mph), this dis-
tance grows to 25 metres
(82 feet)
Practice applying the brakes
with and without an extra load
on the motorcycle, and study its
reactions on various kinds of
road surface.
Work up to the wheel lock limit
gradually.
BMW has a worthwhile safety
contribution to make in this area
too – BMW Safety Training.
These programmes are a won-
derful opportunity: systematic
basic and follow-up training
enables you to master situa-
tions close to the limit and keep
your motorcycle under
supreme control whatever
happens.
