9 TUNING THE CHASSIS

9.1 Checking the basic chassis setting with the rider's weight
401030-01
–
For optimal motorcycle riding characteristics and to avoid
damage to forks, shock absorbers, swingarm and frame, the
basic settings of the suspension components must match the
rider's weight.
–
In the delivered condition, this chassis component is adjusted
for an average rider's weight (with full protective clothing).
Guideline
Standard rider weight 45 … 55 kg (99 … 121 lb.)
–
If the rider's weight is above or below this range, the basic set-
ting of the suspension components must be adjusted accord-
ingly.
–
Smaller differences in the rider's weight can be compensated
for by the fork air pressure.
–
However, if the fork frequently bottoms out (hard end stop on
compression), the fork air pressure must be increased, within
the specified values, to avoid damage to the fork and frame.
9.2 Air suspension WP AER 43 Cone Valve Fork
The fork WP AER 43 Cone Valve Fork combines two leading WP Technologies: the Cone Valve damping system and
the air spring system.
As fork springs are no longer required, a significant weight advantage is achieved when compared to conventional
forks. The response on slightly uneven surfaces is significantly improved.
In normal driving mode, the vehicle balance is provided exclusively by an air cushion. A steel spring is located in
the left fork leg as an end stop.
Info
If the fork is frequently overloaded, then the air pressure in the fork must be increased to avoid damage to
the fork and frame.
The air pressure in the fork can be quickly adjusted for the rider's weight, surface conditions and the rider's pref-
erence using a fork pump. The fork does not have to be detached. The time consuming mounting of harder or
softer fork springs is not required.
If the air chamber loses air due to a damaged seal, the fork will still not sag. In this case the air is retained in the
fork. The suspension travel is maintained as far as possible. The damping becomes harder and the riding comfort
reduces.
As with a conventional fork, the damping can be adjusted in rebound and compression stages.
The rebound adjuster is located at the lower end of the right fork leg.
The compression adjuster is located at the upper end of the right fork leg.
