Brake system GeneralDescending mountain
passes
There is a danger of the
brakes fading if you use
only the rear brakes when
descending mountain passes.
Under extreme conditions, the
brakes could overheat and
suffer severe damage.
Use both front and rear
brakes, and make use of the
engine's braking effect as
well. c

477Riding
Rear wheel lift
Even under severe braking, a
high level of tyre grip can mean
that the front wheel does not
lock up until very late, if at all.
Consequently, ABS does not
intervene until very late, if at all.
Under these circumstances
the rear wheel can lift off the
ground, and the outcome can
be a highsiding situation in
which the motorcycle can flip
over.Severe braking can
cause the rear wheel to
lift off the ground.
Bear in mind that ABS cannot
be relied on in all circumstanc-
es to prevent the rear wheel
from lifting clear of the
ground. c Residual braking function
When the ignition if off, while
self-diagnosis is in progress,
and if a fault develops in the
BMW Integral ABS, only a
residual braking function is
available in the brake circuits
in question. Residual braking
function is the braking per-
formance available without
hydraulic assistance. Under
these circumstances, there-
fore, you must apply consider-
ably 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 sys-
tem in question. When the
residual braking function is active, the integral braking
function is partially or entirely
unavailable.
Without the ABS func-
tion, the wheels may lock
under braking; without braking
power assistance, considera-
bly greater force is required to
brake.
Think well ahead and brake
carefully; avoid severe brak-
ing. Have the fault rectified as
soon as possible by a special-
ist workshop, preferably an
authorised BMW motorcycle
dealer. c

581Accessories
Operating electrical
accessoriesYou can start using electrical
accessories only when the
ignition is switched on. The
auxiliary device remains oper-
ational if the ignition is subse-
quently switched off. Approx.
15 minutes after switching off
the ignition and/or during the
restart operation, the on-
board socket is switched off to
take the load off the vehicle
electrical system.
WiringThe cables from the power
socket to the auxiliary device
must be routed in such a way
that they:
– Do not impede the rider
– Do not restrict or obstruct the steering angle and han-
dling characteristics
– Cannot be trapped
Incorrectly routed cables
can impede the rider.
Route the cables as described
above. c

short ride will lead to misinter-
pretation; this, in turn, means
that the engine will be operat-
ed with the incorrect quantity
of oil.
In order to ensure that the en-
gine oil level is read correctly,
check the oil level only after a
lengthy trip.c
• Make sure the engine is at operating temperature and
hold the motorcycle upright
or place it on the centre
stand, after ensuring that the
ground is level and firm.
• Allow the engine to idle for
one minute.
• Switch off the ignition.
• Read off the oil level. 1
Indicator for engine-oil
level
• Check the oil level in oil-level indicator 1. 2
Maximum engine oil level
3 Minimum engine oil level
The oil level must be between
the MIN and MAX marks. The
difference is approx. 0.5 litres.
If the oil level is below the
MIN mark:
• Top up the engine oil.
If the oil level is above the
MAX mark:
• Correct the level by draining off some of the engine oil.
Damage to the engine
can result if it is operated
without enough oil, but the
same also applies if the oil lev-
el is too high. Always make
sure that the oil level is
correct. c

693Maintenance
Reinstall the cap in the cool-ant filler neck.BrakesA properly functioning brake
system is a basic requirement
for the road safety of your
motorcycle.
Incorrect working prac-
tices endanger the relia-
bility of the brakes. Have all
work on the brake system car-
ried out by a specialist work-
shop, preferably an authorised
BMW motorcycle dealer. cChecking the functionDo not ride the motorcycle if
you have any doubts about the
dependability of the brake
system. In this case: Have the brake system
checked by a specialist
workshop, preferably an
authorised BMW motorcycle
dealer.
Vehicles without ABS
Press the handbrake lever.
» The pressure point must be clearly perceptible.
Press the footbrake lever.
» The pressure point must be
clearly perceptible.
Vehicles with ABS
OE
Switch on the ignition.
Wait for ABS self-diagnosis to complete.
Press the handbrake lever.
» The pressure point must be clearly perceptible.
» The operating noise of the hydraulic pump must be
audible.
Press the footbrake lever. » The pressure point must be
clearly perceptible.
» The operating noise of the hydraulic pump must be
audible.
Brake pads
Brake pads worn past the
minimum permissible
thickness can impair braking
efficiency and under certain
circumstances they can cause
damage to the brake system.
In order to ensure the depend-
ability of the brake system, do
not permit the brake pads to
wear past the minimum per-
missible thickness. c

Maintenance
Without BMW Integral ABS:
• Press the handbrake lever firmly a number of times until
the resistance point is
noticeable.
With BMW Integral ABS
OE:
• Switch on the ignition.
• Wait for self-diagnosis to complete
(b
59).
• Firmly pull the handbrake
lever a number of times, until
the pressure point is
perceptible.
Braking efficiency is im-
paired if the brake pads
are not correctly bedded
against the discs.
Before riding off, always check
that the brakes start to bite
immediately. c
Removing rear wheel
The types of screw used
are listed on (
b
128).c
• Place the motorcycle on the centre stand
OE or a suitable
auxiliary stand.
It is advisable to use the
BMW rear wheel stand
for this purpose (b
108). c •Remove screw
1 from
silencer cover 2.
• Pull the cover to the rear to remove.
•Slacken clamp 3 on the
silencer.
Do not remove the seal-
ing grease from the
clamp. c

A defective bulb places
your safety at risk be-
cause it is easier for other road
users to oversee you and your
motorcycle.
Replace defective bulbs as
soon as possible; always carry
a complete set of spare bulbs
if possible. c
The types of bulb used
are listed on (
b
139). c
Do not touch the glass of
new bulbs with your fin-
gers. Use a clean, dry cloth to
hold the bulbs when handling
them. Dirt deposits, in particu-
lar oil and grease, interfere
with heat radiation from the
bulb. This leads to overheating
and shortens the bulb’s oper-
ating life. c The types of threaded
fastener used are listed
on (
b
128). c
Replacing low-beam
headlight bulb
If it is not standing firmly,
the motorcycle could
topple in the course of the
operations described below.
Make sure that the motorcycle
is steady on its stand. c
The bulb is pressurised
and can cause injury if
damaged.
Wear protective goggles and
gloves when changing
bulbs. c
Turn the handlebars to
the right to facilitate
access. c High-beam headlight
1 and
low-beam headlight 2 are
accessible from behind.
• Switch off the ignition.
•Turn cover 3 counter-clock-
wise and remove it.

• The procedure for changing the high-beam headlight
bulb is the same as that for
the low-beam bulb. Note,
however, that the high-beam
headlight bulb is held in
place by a single-leg, vertical
spring clip.Replacing parking light
If it is not standing firmly,
the motorcycle could
topple in the course of the
operations described below.
Make sure that the motorcycle
is steady on its stand. c• Switch off the ignition.
• Remove securing screws

on both sides of the bulb
housing. • Pull the bulb housing for-
ward and tilt it slightly down.
• Turn bulb holder 2 counter-
clockwise to remove it from
the headlight housing.
• Remove bulb 3 from the bulb
holder.
Installation is the reverse of the
removal procedure.
• Use a clean, dry cloth to hold the new bulb.
