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
z
the 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
information from your authorised
BMW Motorrad dealer or on
the Internet 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, preferably
an authorised BMW Motorrad
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.
