Tire recommendation
For every tire size,
BMW Motorrad has tested and
approved certain tire brands as
roadworthy. BMW Motorrad
cannot evaluate the suitability of
any other tires, and can therefore
take no responsibility for their
riding safety.
BMW Motorrad recommends
only using the tires tested and
approved by BMW Motorrad.
Detailed information can be
obtained from your authorized
BMW Motorrad Retailer or online

Effect of wheel sizes
on suspension control
systems
The wheel sizes play a major role
in the ABS and ASC suspension-
control systems. The diameter
and width of the wheels stored
in the control unit have particular
significance as the basis for all
necessary calculations. A change
in these sizes resulting from con-
version to wheels not installed
as standard equipment can seri-
ously affect the control efficiency
of these systems.
The sensor rings required for
wheel speed detection must also
match the installed control sys-
tems and may not be replaced.
If you want to convert your
motorcycle to different wheels,
please contact a specialist
workshop, preferably a
BMW Motorrad retailer. In some
cases, the data stored in the
control units can be adapted for
the new wheel sizes.
Removing the front wheel
Park motorcycle. Ensure that
the ground is firm and level.
Remove screw 1 and remove
wheel speed sensor from the
