Check spokes
Make sure the ground is level
and firm and place the motor-
cycle on its stand.
Draw the handle of a screw-
driver or a similar instrument
across the spokes and listen
to the notes of the individual
spokes.
If the notes vary:
Have the spokes checked by a
specialist workshop, preferably
an authorised BMW Motorrad
dealer.
Check the tyre tread
depth
Your motorcycle's handling
and grip can be impaired
even before the tyres wear to
the minimum tyre tread depth
permitted by law.
Have the tyres changed in good
time before they wear to the
minimum permissible 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.
Wear indicators are built
into the main profile
grooves on each tyre. 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 is worn to min-
imum:
Replace tyre or tyres, as applic-
able.
Chain
Lubricating chain
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.
Lubricate the drive chain every
1000 km at the latest. Lubric-
ate the chain more frequently if
the motorcycle is ridden in wet,
dusty or dirty conditions.
Switch the ignition off and se-
lect neutral.
Clean the drive chain with a
suitable cleaning product, dry it
and apply chain lubricant.
Wipe off excess lubricant.
