use of available braking per-
formance in an emergency.
BMW Integral ABS provides
improved braking deceler-
ation by means of anti-lock
braking for both wheels and
braking force distribution by
means of the integral brak-
ing function. Making full use
of the motorcycle's technical
braking capacity will minimise
braking distances noticeably,
even when road conditions
are poor. When the motor-
cycle is ravelling in a straight
line, BMW Integral ABS en-
ables safe optimised emer-
gency braking adapted to
match the road-surface con-
ditions.Reserves for safetyThe potentially shorter brak-
ing distances which BMW
Integral ABS permits must
not be used as an excusefor careless riding. ABS is
primarily a means of ensur-
ing a safety margin in genuine
emergencies.
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.
Partially integral brakesYour motorcycle is equipped
with partially integral brakes.
Both front and rear brakes
are applied when you pull the
handbrake lever. The foot-
brake lever acts only on the
rear brake.
The electronic controller in
the BMW Integral ABS regu-
lates braking-force distribu-
tion between front and rear
wheels. Braking-force distri-
bution depends on load andis recalculated every time the
ABS controller comes into ac-
tion.
Brake boosterThe hydraulic pump in the
BMW Integral ABS boosts
the braking force acting on
the wheel when the brakes
are applied. By boosting the
braking force in this way,
BMW Integral ABS achieves
higher braking efficiency than
standard brake systems.ABS anti-lock braking
systemABS prevents the wheels
locking under braking, thus
contributing significantly to
road safety.

counter-clockwise.
Installation of the turn indic-

Use a clean, dry cloth to
hold the new bulb.
Jump starting
The wires leading to the
power socket do not
have a load-capacity rating
adequate for jump-starting
the engine. Excessively high
current can lead to a cable fire or damage to the vehicle
electronics.
Do not use the on-board
socket to jump-start the
engine of the motorcycle.
Touching live parts of
the ignition system with
the engine running can cause
electric shock.
Do not touch parts of the igni-
tion system when the engine
is running.
A short-circuit can result
if the crocodile clips of
the jump leads are accident-
ally brought into contact with
the motorcycle.
Use only jump leads fitted
with fully insulated crocodile
clips at both ends.
Jump-starting with a
donor-battery voltage
higher than 12 V can damage
the vehicle electronics.

About BMW Motorrad Integral ABS
How does ABS work?
The maximum braking force
it is possible to transfer to the
carriageway depends, among
other things, on the road
surface's coefficient of friction.
Gravel, ice and snow, and
water on the road, have
significantly poorer coeffi-
cients of friction than a dry,
clean asphalt road surface.
The poorer the road's coeffi-
cient of friction, the longer the
braking distance.
If the maximum braking force it
is possible to apply to the road
is exceeded when the rider
increases brake pressure, the
wheels will begin to lock and
directional stability is lost; a fall
threatens. Before this situation
can arise, ABS intervenes and adapts the braking pressure to
the maximum braking force
it is possible to transfer so that
the wheels continue to turn
and driving stability is main-
tained whatever the prevailing
road conditions.
What happens with bumps
in the road?
Corrugated road surfaces or
bumps in the road can cause
the tyres to temporarily lose
contact with the road surface
and hence the braking force it
is possible to apply to drop to
zero. If the brakes are applied
in this situation, the ABS must
reduce the braking pressure to
ensure driving stability when
contact with the road surface
is restored. At this moment,
BMW Motorrad Integral ABS must assume extremely low
coefficients of friction (gravel,
ice, snow) so that the wheels
turn in any conceivable situa-
tion and thus the stability of
the motorcycle is ensured.
Once the actual circum-
stances are detected, the
system will set the brake pres-
sure to the optimum value.
What do we observe during
rider safety training?
Braking in which ABS has to
intervene has, by comparison
with normal braking, a signifi-
cantly higher demand for
electricity which puts a heavy
load on the battery. The
battery is constantly being
charged in normal riding so
that it always has sufficient
capacity available. Info_I_ABS_en_xx.fm Seite 1 Dienstag, 19. Juli 2005 2:48 14
