ures for checking and replacing
certain wear parts.
Special tightening torques are lis-
ted as applicable. The tightening
torques for the threaded fasten-
ers on your motorcycle are listed
in the section entitled "Technical

You will find information on more
extensive maintenance and re-
pair work in the Repair Manual
on DVD/CD-ROM (RepROM) for
your motorcycle, which is avail-
able from your authorised BMW

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.
The oil level varies with the
temperature of the oil. The
higher the temperature, the high-
er the level of oil in the sump.
865zMaintenance

Checking the oil level with the
engine cold or after no more than
a short ride will lead to misinter-
pretation; 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.
Allow the engine to idle until
the fan starts up, then allow it
to idle one minute longer.
Make sure the ground is level
and firm and hold the motor-
cycle upright.
Switch off the engine.
Wipe the area around the oil
filler neck clean.Remove oil dipstick1by turn-
ing it counter-clockwise.
Wipe the oil off MIN-MAX part
of dipstick2with a clean, dry
cloth.Turn the oil dipstick clockwise
to install.
Remove the oil dipstick and
check the oil level.
Engine oil, specified level
Engine oil, 15W-40
Between MIN and MAX
marks
If the oil level is below the MIN
mark:
Top up the engine oil ( 67)
866zMaintenance

If the oil level is above the MAX
mark:
Have the oil level corrected by
a specialist workshop, prefer-
ably an authorised BMW Mo-
torrad dealer.Topping up engine oil
Damage to the engine
can result if it is operated
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.Remove oil dipstick1.
Top up the engine oil until the
level reaches markA.
Check the engine oil level
( 65)
Install the oil dipstick.
Brake systemDependability of the brake
systemA fully functional brake system is
a basic requirement for the road
safety of your motorcycle.
Do not ride the motorcycle if you
have any doubts about the de-
pendability of the brake system.
Under these circumstances have
the brake system checked by a
specialist workshop, preferably
an authorised BMW Motorrad
dealer.
Incorrect working practices
endanger the reliability of
the brakes.
Have all work on the brake sys-
tem performed by a specialist
workshop, preferably an author-
ised BMW Motorrad dealer.
867zMaintenance

Checking operation of
brakesPull the handbrake lever.
The pressure point must be
clearly perceptible.

The pressure point must be
clearly perceptible.
If pressure points are not clearly
perceptible:
Have the brakes checked by a
specialist workshop, preferably
an authorised BMW Motorrad
dealer.
Brake padsChecking front brake pad
thickness
Brake pads worn past
the minimum permissible
brake-pad thickness can cause
a reduction in braking efficiency
and under certain circumstances
they can cause damage to the
brake system.
In order to ensure the dependab-
ility of the brake system, do not
permit the brake pads to wear
past the minimum permissible
brake-pad thickness.Visually inspect the brake pads
to ascertain their thickness.
Viewing direction: Between
wheel and fork tube toward the
brake caliper.
Brake-pad wear limit,
front
min 1 mm (Friction pad only,
without backing plate)
The wear indicators
(grooves) must be clearly
visible.

no longer clearly visible:
Have the brake pads replaced
by a specialist workshop,
preferably an authorised BMW
Motorrad dealer.Checking rear brake pad
thicknessMake sure the ground is level
and firm and place the motor-
cycle on its stand.
Brake pads worn past
the minimum permissible

a reduction in braking efficiencyand under certain circumstances
they can cause damage to the
brake system.
In order to ensure the dependab-
ility of the brake system, do not
permit the brake pads to wear
past the minimum permissible
brake-pad thickness.

869zMaintenance

A low fluid level in the
brake reservoir can allow air
to penetrate the brake system.
This significantly reduces braking
efficiency.
Check the brake-fluid level at
regular intervals.
Check the brake fluid level in
front reservoir1.
Wear of the brake pads
causes the brake fluid level
in the reservoir to sink.Brake fluid level, front

If the brake fluid level drops be-
low the permitted level:
Have the defect rectified as
quickly as possible by a spe-
cialist workshop, preferably
an authorised BMW Motorrad
dealer.
