Effect of wheel size on ABS
The wheel sizes are very im-
portant for the ABS. In par-
ticular, the diameter and the
width of a vehicle's wheels are
programmed into the control
unit and are fundamental to
all calculations. Any change
to these dimensions, caused
for example by a switch to
wheels other than the stand-
ard installed ones, can seriously
affect the performance of the
control systems.
The sensor rings are essential
for correct wheel speed detec-
tion; they too must match the
motorcycle's control systems
and consequently cannot be re-
placed.
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
beforehand, preferably an
authorised BMW Motorrad
retailer. In some cases, the
data programmed into the
control units can be changed to
suit the new wheel sizes.
Removing front wheel
Place the motorcycle
on an auxiliary stand.
BMW Motorrad recommends
you use the BMW Motorrad
rear-wheel stand.
Install the rear-wheel stand
( 73).
Lift the front of the motor-
cycle until the front wheel is
clear of the ground, preferably
using a BMW Motorrad front-
wheel stand.
Install the front-wheel stand
( 73).
