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.
BMW Motorrad recommends
using only tyres tested by
BMW Motorrad.
It is absolutely essential to ob-
serve the maximum permissible
speed and load-capacity ratings
(see "Technical data").
Comply with the instructions re-
garding maximum speed for rid-
ing with knobbly tyres or winter
tyres fitted ( 71).
You can obtain detailed
information from your authorised
BMW Motorrad dealer or on
the Internet at www.bmw-

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 particular,
the diameter and the width of a
vehicle's wheels are programmed
into the control unit and are fun-
damental to all calculations. Any
change in these influencing vari-
ables, caused for example by a
switch to non-standard installed
wheels, 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.
