General instructionsThe 'Maintenance' chapter
describes work involving the
replacement of wear parts
that can be performed with
minimum effort.
Special tightening torques are
listed as applicable.
If you are interested in inform-
ation on more extensive work,
we recommend the repair
manual on CD-ROM which
applies to your particular mo-

Engine oilChecking engine oil level
The engine can seize if
the oil level is low, and
this can lead to accidents.
Always make sure that the oil
level is correct.
Oil can collect in the
sump if the motorcycle
is out of use for an extended
period of time; this oil has to
be pumped into the oil tank
before the level is read. The
engine oil must be at oper-
ating temperature to do this.
Checking the oil level with the engine cold or after no more
than a short ride will lead to
misinterpretation; this in turn,
means that the engine will be
operated 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.
The oil level varies with
the temperature of the
oil. The higher the temperat-
ure the higher the oil level in
the oil tank. Check the engine
oil level immediately after a
lengthy journey.
Make sure the engine is at
operating temperature and
hold the motorcycle upright.

Damage to the engine
can result if it is oper-
ated without enough oil, but
the same also applies if the oil
level is too high.
Always make sure that the oil
level is correct.
Wipe the area around the
filler neck clean.

Brake system, generalReliabilityA fully functional brake sys-
tem is a basic requirement for
the road safety of your motor-
cycle.
Do not ride the motorcycle if
you have any doubts about
the dependability of the brake
system.
Under these circumstances
have the brake system
checked by a specialist
workshop, preferably an
authorised BMW Motorrad
dealer.
Incorrect working prac-
tices endanger the reli-
ability of the brakes.
Have all work on the brake
system performed by a spe-
cialist workshop, preferably

thickness, front brakes
Brake pads worn past
the minimum permissible
thickness can cause a reduc-
tion in braking efficiency and
under certain circumstances
they can cause damage to
the brake system.
In order to ensure the de-
pendability of the brake sys-
tem, do not permit the brake pads to wear past the minim-
um permissible thickness.
Make sure the ground is
level and firm and place the
motorcycle on its stand.
Visually inspect the left and
right brake pads to ascer-
tain their thickness. Viewing

The wear indicators on
the brake pads must be
clearly visible.
If the wear indicating mark is
no longer clearly visible: Have the brake pads re-
placed by a specialist work-
shop, preferably an author-
ised BMW Motorrad dealer.

Brake fluidCheck the brake-fluid
level, front brakes
A low fluid level in the
brake reservoir can al-
low air to penetrate the brake
system. This significantly re-
duces braking efficiency.
Check the brake-fluid level at
regular intervals.
Make sure the ground is
level and firm and hold the
motorcycle upright.
Move the handlebars to the
straight-ahead position.
