Tyre recommendation
For each size of tyre BMW
Motorrad tests certain makes,
and approves those that it
certifies as roadworthy. If BMW
Motorrad has not approved the
wheels and tyres, it cannot
assess their suitability or provide
any guarantee of road safety.
Use only wheels and tyres ap-
proved by BMW Motorrad for
your type of motorcycle.
You can obtain detailed informa-
tion from your authorised BMW
Motorrad dealer or on the Inter-
net at www.bmw-motorrad.com.
Effect of wheel size on
ABS
Wheel size is very important as a
parameter for the ABS. In partic-
ular, the diameter and the width
of a motorcycle'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, prefer-
ably an authorised BMW Motor-
rad dealer. In some cases, the
data programmed into the control
units can be changed to suit the
new wheel sizes.
RDC label
with tyre pressure monitoring
(RDC)
OE
Incorrect tyre fitting can
damage the RDC sensors.
Be sure to explain to the au-
thorised BMW Motorrad dealer
or the specialist 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.
