system. This significantly re-
duces braking efficiency.
Check the brake-fluid level at
regular intervals.

ably an authorised BMW

filled with a special hy-
draulic fluid that does not
have to be changed.TyresCheck the 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 is worn to
minimum:
Replace tyre or tyres, as ap-
plicable.
RimsChecking rimsMake 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.
WheelsApproved wheels and
tyresFor 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-
ility or provide any guarantee
of road safety.
Use only wheels and tyres ap-
proved by BMW Motorrad for
your type of motorcycle.

Incorrect tyre-removal
procedures can result in
damage to the RDC sensors.
Be sure to notify the author-
ised BMW Motorrad dealer or
specialist workshop that the
wheel is fitted with an RDC
sensor. If the motorcycle is equipped
with RDC, each wheel rim
bears an adhesive label indic-
ating the position of the RDC
sensor. When changing the
tyre, take care not to damage
the RDC sensor. Be sure to
draw the attention of the au-
thorised BMW Motorrad deal-
er or specialist workshop to
the fact that the wheel is fitted
with an RDC sensor.

ring; it is very important to en-
sure that the correct sensor
ring is installed. Install only
the sensor ring that matches
the motorcycle's construction
status.
Threaded fasteners not
tightened to the spe-
cified torque can work loose
or their threads can suffer
damage.
Always have the security of
the fasteners checked by a
specialist workshop, prefer-
ably an authorised BMW Mo-
torrad dealer.
The front wheel must be
installed right way round to rotate in the correct direc-
tion.
Note the direction-of-rotation
arrows on the tyre or the
wheel rim.
There is a risk of dam-
aging parts of the front
