Wheels

Effect of wheel size on
chassis and suspension
control systems
Wheel size is very important
as a parameter for the chassis
and suspension control sys-
tems ABS and ASC. In particu-
lar, the diameter and the width
of a vehicle's wheels are pro-
grammed into the control unit
and are fundamental to all cal-
culations. Any change in these
influencing variables, caused for
example by a switch to wheels
other than those installed ex-
works, can have serious effects
on the performance of the con-
trol 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.

ATTENTION
Tyre removal not in compli-
ance with correct procedure
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.
When changing the tyre, take
care not to damage the RDC
