tyres
Risk of accident due to poorer

Replace the worn tires.

Wheels

Affect of wheel sizes
on suspension control
systems
The wheel sizes play a major
role in the ABS and ASC/DTC
suspension-control systems. The
diameter and width of the wheels
stored in the control unit have
particular significance as the ba-
sis for all necessary calculations.
A change in these sizes resulting
from conversion to wheels not
installed as standard equipment
can seriously 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 equip your
motorcycle with different wheels,
please contact a specialist
service facility, preferably a
BMW Motorrad retailer. In some
