If the wear indicating marks are
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
brake-pad thickness can cause
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.
Visually inspect rear brake
pads1from behind to
ascertain their thickness.

The wear indicators must be
clearly visible.
If the wear indicating marks are
no longer visible:
Have the brake pads replaced

and firm and hold the motor-
cycle upright.
Move the handlebars to the
straight-ahead position.
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

Have the defect rectified as
quickly as possible by a spe-
cialist workshop, preferably
an authorised BMW Motorrad
dealer.

TyresChecking tyre tread depthMake sure the ground is level
and firm and place the motor-
cycle on its stand.
Measure the tyre tread depth
in the main tread grooves with
wear marks.
Tyres have wear indicators
integrated into the main
tread grooves. The tyre is worn
out when the tyre tread has worn
down to the level of the marks.
The locations of the marks are
indicated on the edge of the tyre,
e.g. by the letters TI, TWI or by
an arrow.
If the tyre tread no longer com-
plies with the minimum legally
required tread depth:
Replace tyre.
RimsChecking rimsMake sure the ground is level
and firm and place the motor-
cycle on its stand.
Visually inspect the rims for
defects.
Have damaged rims checked
and, if necessary, replaced by a
specialist workshop, preferably
an authorised BMW Motorrad
dealer.ChainLubricating chainSwitch the ignition off and se-
lect neutral.
Dirt, dust and inadequate
lubrication will result in ac-
celerated wear and significantly
shorten the drive chain's useful
life.
Clean and lubricate the drive
chain at regular intervals.

Clean the drive chain with a
suitable cleaning product, dry it
and apply chain lubricant.
Wipe off excess lubricant.Checking chain tensionMake sure the ground is level
