For this reason, check the
details in the following sections
before you start the journey:
–Fuel level
– Positions of the handlebar-
lever fittings
– Brake fluid level
– Clutch fluid level
– Brakes
– Warning lights and telltale
lights
– Lights
– Shock-absorber setting and
spring preload
– Wheel rim and tyre condition,
tread depth and tyre
pressures
– Load, gross weight –
Check regularly (every time
you stop for fuel), on the basis
of the following section:
– Engine-oil level
(every 2nd/3rd stop for fuel):
– Brake pads
If you encounter any problems
or difficulties, it is always best to
contact your authorised
BMW motorcycle dealer. He will
provide the necessary advice
and assistance.

Residual braking function
d Warning:
When the ignition is switched
off, before and during self-
diagnosis (
b 72) or if the
BMW Integral ABS develops a
fault, only a RESIDUAL BRAK-
ING FUNCTION (
b 71) remains
available for slowing the
motorcycle.
When the RESIDUAL BRAK-
ING FUNCTION is active, 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 BRAK-
ING FUNCTION is active, the
ABS function is unavailable
in the brake systems in
question.
2(Optional extra
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.
\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).

Wheels
d Warning:
Use only wheels and tyres
that BMW Motorrad has ap-
proved for your motorcycle.
For each size of tyre BMW
tests certain makes, and ap-
proves those that it certifies
as roadworthy.
If BMW Motorrad has not ap-
proved the wheels and tyres
it cannot assess their suita-
bility or provide any guaran-
tee of road safety. You can
obtain detailed information
from your authorised BMW
motorcycle dealer or by
visiting
www.bmw-motorrad.com on
the Internet.
Checking wheel rims
d Warning:
Have damaged wheel rims
checked and, if necessary,
replaced by a specialist work-
shop, preferably an author-
ised BMW motorcycle dealer.
Checking tyre tread
d Warning:
Comply with statutory legal
requirements concerning
minimum tread depth. Worn
tyres can impair handling.
 Measure tread depth at the
centre of the tyre tread
BMW's minimum tread depth
recommendation:
Front ............................... 2 mm
Rear ................................ 3 mm

Checking tyre pressures
d Warning:
Incorrect tyre pressures have
a considerable influence on
handling and on tyre life.
Adjust tyre pressures to suit
total weight. Never exceed ei-
ther the motorcycle ’s gross
weight or the individual wheel
load limits (b 47). –
When tyres are cold:
 Remove valve caps
 Check/correct tyre pressure
Tyre pressures: Front Rear
One-up 2.2 bar 2.5 bar
Two-up 2.5 bar 2.7 bar
Two-up
with luggage 2.5 bar 2.9 bar
 Fully tighten valve caps
Fully tightening valve caps
d Warning:
At high road speeds, tyre
valves have a tendency to
open as a result of centrifugal
force.
Use only metal valve caps
with rubber seals.
Valve caps that are screwed
on well prevent air from es-
caping suddenly.

e Attention:
Do not exceed the gross weight
limit of 450 kg.
Do not exceed the wheel load
limits of 180 kg at the front and
300 kg at the rear.
Set the shock absorbers,
spring preload and tyre pres-
sures to suit gross weight
(
b 41, 42, 44).
The gross weight consists of:
– Motorcycle with full tank
– Rider
– Passenger
–Luggage

Brake system - with BMW Integral ABS2(
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.
2(Optional 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 70). 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 ABS2(
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, BMW Integral ABS
achieves higher braking effi-
ciency than conventional 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.
