compensated with the air pres-
sure tester at the filling station.
Example: According to the
Rider's Manual, the tire inflation
pressure is to be 36 psi (2.5 bar),
however 33 psi (2.3 bar) is
shown in the multifunction
display. The tester at the
filling station indicates 34.8 psi
(2.4 bar). This value must be
increased by 3 psi (0.2 bar) to
37.8 psi (2.6 bar) in order to
produce the correct tire inflation
pressure.

Chassis adjustments
The proper loading state must
first be selected when the mo-
torcycle is stationary according to
the motorcycle's load. Depend-
ing on the riding mode selected,
the damping levels are set on
both spring struts and the spring
base and spring rate are set on
the rear spring strut. If the se-
lected riding mode is changed,
the spring rate on the rear spring
strut is also adjusted in addition
to the damping of both spring
struts. This enables very precise
adjustment of the chassis to all
riding conditions, 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.
