Wheels

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
z
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
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.
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.
Removing front wheel
Make sure the ground is level
and firm and place the motor-
cycle on its stand.
Remove screw 1 and remove
the wheel-speed sensor from
its bore.
