Effect of wheel size
on suspension-control
systems
Wheel size is very important as
a parameter for the suspension-
control systems ABS and ASC.
In particular, the diameter and the
width of a motorcycle's wheels
are programmed into the control
unit and are fundamental to all
calculations. 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 import-
ant to consult a specialist work-
shop beforehand, preferably an
authorised BMW Motorrad deal-
er. In some cases, the data pro-
grammed into the control units
can be changed to suit the new
wheel sizes.
RDC label
with tyre pressure monitoring
(RDC)
OE
Incorrect tyre-removal pro-
cedures can result in dam-
age to the RDC sensors.
Be sure to notify the authorised
BMW Motorrad dealer or spe-
cialist workshop 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
sensor. Be sure to draw the
attention of the authorised BMW
Motorrad dealer or specialist
workshop to the fact that the
wheel is fitted with an RDC
sensor.
Remove the front wheel
Make sure the ground is level
and firm and place the motor-
cycle on its centre stand.
