Unsuitable hydraulic flu-
ids could cause damage
to the clutch system.
Do not attempt to top up
the system with fluids of any
kind.
Have the defect rectified
as quickly as possible by a
specialist workshop, prefer-
ably an authorised BMW
Motorrad dealer.
Tyres
Checking tyre tread
depth
Your motorcycle's hand-
ling and grip can be im-
paired 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
motorcycle on its stand.
Measure the tyre tread
depth in the main tread
grooves with wear marks.
Tyres have wear indic-
ators 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 loca-
tions of the marks are indic-
ated on the edge of the tyre,
e.g. by the letters TI, TWI or
by an arrow.
If the tyre tread no longer
complies with the minimum
legally required tread depth:
Replace tyre.
Rims
Checking rims
Make sure the ground is
level and firm and place the
motorcycle 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.
Wheels
Approved wheels and
tyres
For each size of tyre BMW
Motorrad tests certain makes,
and approves those that it
certifies as roadworthy. If
BMW Motorrad has not ap-
proved the wheels and tyres,
it cannot assess their suitab-
