Chassis adjustments
The proper type of loading must
first be selected when the mo-
torcycle is stationary according to
the motorcycle's load. Depend-
ing on the damping selected for
this purpose, the damping lev-
els are set on both spring struts
and the spring base and spring
rate are set on the rear spring
strut. If the selected damping
is changed, the spring rate on
the rear spring strut is also ad-
justed in addition to the damping
of both spring struts. This en-
ables very precise adjustment of
the chassis to all riding condi-
tions, including while riding.
The combination of spring
base, damping and spring rate
ensures the chassis geometry
is always appropriate.
The static normal position is
virtually maintained while riding.
The different riding and loading
conditions are offset so that
the handling of the motorcycle
remains constant.
It is possible to electrically
change the spring rate
through the combination of a
conventional coil spring with a
plastic element (Elastogran), the
lateral expansion of which can be
electrohydraulically limited using
a displaceable sleeve. The more
the sleeve surrounds the plastic
element, the more its expansion
is limited and the spring rate
increases. The highest spring
rate is achieved when the sleeve
completely encloses the plastic
element and sits on the steel
spring. Accordingly, the spring
rate is lower, the less the sleeve
limits the expansion of the plastic
element.
