Affect of wheel sizes
8
on suspension control
systems

The wheel sizes play a major role
with the ABS system. The di-
ameter and width of the wheels
stored in the control unit have
particular significance as the
basis for all necessary calcula-
tions. A change in these sizes
due to conversion to others than
the wheels installed as standard
equipment can seriously affect
z
the control comfort of the sys-
tem.
The sensor wheels required for
wheel speed detection must also
match the system installed 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 Dealer. In some
cases the data stored in the
control unit can be adapted to
the new wheel sizes.
