Effect of wheel size
on suspension-control
systems
Wheel size is very important as
a parameter for the suspension-
control systems ABS and ASC.
In particular, the diameter and the
width of a motorcycle's wheels
are programmed into the control
unit and are fundamental to all
calculations. 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-
