Effect of wheel size on
chassis and suspension
control systems
Wheel size is very important as
a parameter for the frame and
suspension control systems ABS
and ASC/DTC. In particular, the
diameter and the width of the
vehicle's wheels are programmed
into the control unit and are fun-
damental to all calculations. Any
change in these influencing vari-
ables, caused for example by
a switch to wheels other than
those installed ex-works, can
have serious effects on the per-
formance of the control systems.
The sensor rings are essential
for correct road-speed calcula-
tion, and they too must match
the motorcycle's control sys-
tems and consequently cannot
be changed.
If you decide that you would like
to fit non-standard wheels to
your motorcycle, it is very im-
portant to consult a specialist
workshop beforehand, preferably
an authorised BMW Motorrad
dealer. In some cases, the data
programmed into the control
units can be changed to suit the
new wheel sizes.

Damage to RDC sensors
Be sure to explain to the spe-
cialist workshop or authorised
BMW Motorrad dealer that the
wheel is fitted with an RDC
sensor.
If the motorcycle is equipped
with RDC, each wheel rim bears
an adhesive label indicating the
position of the RDC sensor.

special care must be taken not
