Tyres
Checking tyre tread depth
Make 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.
Rims
Checking rims
Make 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.
Chain
Checking chain tension
Make sure the ground is level
and firm and place the motor-
cycle on its stand.
Use a screwdriver to push the
chain up and down and meas-
ure difference A.
Chain deflection
25...30 mm (Motorcycle sup-
ported on its side stand)
30...35 mm (Rear suspen-
sion extended)
If measured value is outside per-
mitted tolerance:
Adjust the chain tension
