Recommended tyres
For each size of tyre BMW Mo-

of road safety for other tyres.
BMW Motorrad recommends
using only tyres tested by BMW

Effect of wheel size
on suspension-control
systems
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 sys-
tem.
The sensor rings are essential for
correct road-speed calculation,
and they too must match the
motorcycle's system and con-
sequently 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 unit
can be changed to suit the new
wheel sizes.
