Tyre recommendation
For each size of tyre
BMW Motorrad tests and
classifies as roadworthy certain

assess the suitability or provide
any guarantee of road safety for
other tyres.
BMW Motorrad recommends
using only tyres tested by

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
