Running in
Running in new tyres
d Warning:
New tyres have a smooth sur-
face. This must be roughened
by riding in a restrained man-
ner at various heel angles
until the tyres are run in.
This running in procedure is
essential if the tyres are to
reach their maximum level of
grip.
Running in
new brake pads
d Warning:
New brake pads must “bed
down” and therefore do not
achieve their optimum friction
levels during the first 500 km
(300 miles).
This slight initial reduction in
braking efficiency can be
compensated for by exerting
greater pressure on the lever.
Try to avoid all unnecessary
hard braking during this initial
period.
e Attention:
Comply with the notes on BMW
Integral ABS (b 84-91).

ABS warning lightThe ABS warning light 1 lights
up if the BMW Integral ABS
develops a fault (
b91).
Warning light, general General warning light 2 lights
up if the BMW Integral ABS
develops a fault (
b91), or if the
tail light or brake light is defec-
tive.
Low fuel levelWhen warning light 3 comes on,
there are still approx. 4 litres
(0.9 Imp.gal.) of fuel in the tank.
*n depending on national-market
specification
Engine oil pressureWarning light 4 goes out above
idle speed.
e Attention:
If warning light 4 comes on dur-
ing the journey, take the follow-
ing action as soon as traffic
conditions permit:
 Disengage the clutch
 Operate the kill switch
 Bring the motorcycle safely to a halt
 Check engine oil level (
b43)
Top up with fresh oil if the oil
level is low. If the warning light
for engine oil pressure lights up
even though the oil level is cor-
rect, it is absolutely essential to
consult a specialist workshop,
preferably an authorised BMW
motorcycle dealer.

Brake system - general
Wet brakesAfter the motorcycle has been
washed, ridden through water
or ridden in the rain, the brake
discs and pads may be wet (or
iced-over in winter), and may
not take effect immediately.
d Warning:
The brakes have to dry before
they start to bite.
Salt on brakesThe brakes may fail to take
effect immediately if the motor-
cycle was ridden on salt-cov-
ered roads and the brakes were
not applied for some time.
d Warning:
The layer of salt on the brake
discs and pads has to be
worn off before the brakes
start to bite.

Brake system - general
Oil and grease on brakes
d Warning:
Brake discs and pads must be
free from oil or grease.
Dirt or mud on brakesWhen you ride on loose sur-
faces or muddy roads, the
brakes may fail to take effect
immediately because of dirt or
moisture on the discs or brake
pads.
d Warning:
The brakes must first be
applied until the discs and
pads are clean.
Dirt on the brakes increases
the rate of pad wear.
d Warning:
If the brake lever can be
moved right to the limit of its
travel, this indicates a me-
chanical or hydraulic fault.
The brake system is defec-
tive.
Immediately consult a spe-
cialist workshop, preferably
an authorised
BMW motorcycle dealer.

Brake system - with BMW Integral ABS
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. 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
(
b86). 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.

Extra safety reservesBut 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
Fully integral brakesThe integral brake function
interlinks the front and rear
brakes, so both wheels are
braked when you operate a
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.
Braking-force distribution
depends on load and is recal-
culated every time the ABS
controller comes into action.
In a fully integral brake configu-
ration, the integral braking func-
tion is activated by either the
handbrake lever or the brake
pedal.
Brake boosterThe 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 sys-
tem
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 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-
thorised BMW motorcycle
dealer.
L Note:
When the RESIDUAL BRAKING
FUNCTION for the front brake is
active, it is advisable to set ad-
juster A (
b47) of the hand-
brake lever to position 4.
The RESIDUAL BRAKING
FUNCTION is active under the
following circumstances:
– Ignition off
– Before and during self-diag- nosis (
b88)
– Fault in the BMW Integral ABS (
b91)
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.
