Tire recommendation
For every size of tire,
BMW Motorrad has tested and
approved certain makes as
roadworthy. BMW Motorrad
cannot evaluate the suitability of
other tires, and can therefore
take no responsibility for their
driving safety.
BMW Motorrad recommends
only using the tires tested and
approved by BMW Motorrad.
Extensive information is
available at your authorized
BMW Motorrad retailer or on
the Internet at www.bmw-
motorrad.com.
Affect of wheel sizes on
chassis control systems
The wheel sizes play a major role
in the chassis control systems
ABS and DTC. Especially the di-
ameter and width of the wheels
are stored in the control unit as
the basis for all necessary calcu-
lations. A change in these sizes
due to conversion to others than
the wheels installed as standard
equipment can seriously affect
the control comfort of these sys-
tems.
The sensor wheels required for
wheel speed detection must also
match the control systems in-
stalled and may not be replaced.
If you want to equip your mo-
torcycle with different wheels,
please speak to a specialist ser-
vice facility, and preferably a
BMW Motorrad retailer. In some
cases the data stored in the con-
trol units can be adapted to the
new wheel sizes.
Removing front wheel
