Affect of wheel sizes on
chassis control systems
The wheel sizes play a major role
in the ABS and ASC chassis
control systems. Especially the
diameter and width of the wheels
are stored in the control unit as
z
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
motorcycle with different wheels,
please speak to a specialist
service facility, and preferably a
BMW Motorrad retailer. In some
cases the data stored in the
control units can be adapted to
the new wheel sizes.
