RIMS AND TYRES
Checking rims
Place the motorcycle on its
stand on firm, even ground.
Visually inspect the rims for
defects.
Have damaged rims inspec-
ted by a specialist workshop
and replaced if necessary,
preferably by an authorised
BMW Motorrad Retailer.
Checking spokes
Place the motorcycle on its
stand on firm, even ground.
Use a screwdriver handle or
similar object to brush over
the spokes and pay attention
to the sequence of sounds.
If the sequence of sounds is
irregular:
Have the spokes checked
by a specialist workshop,
preferably by an authorised
BMW Motorrad Retailer.
WHEELS
Tyre recommendation
For each size of tyre,
BMW Motorrad tests and
classifies as roadworthy certain
makes. BMW Motorrad cannot
assess the suitability or provide
any guarantee of road safety
for other tyres.
BMW Motorrad recommends
using only tyres tested by
BMW Motorrad.

Effect of wheel size on
chassis and suspension
control systems
Wheel size is very important as
a parameter for the suspension
control systems. In particular,
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 important to con-
sult a specialist workshop
