10 TUNING THE CHASSIS

10.1 Checking the basic chassis setting with the rider's weight
Info
When adjusting the basic chassis setting, first adjust the shock absorber and then the fork.

–
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.
–
As delivered, Husqvarna motorcycles are 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
setting of the suspension components must be adjusted
accordingly.
–
Small weight differences can be compensated by adjust-
ing the spring preload, but in the case of large weight differ-
ences, the springs must be replaced.
10.2 Air suspension AER 43
Air suspension WP Performance Systems AER 43 is used in the fork.
In this system, suspension is located in the left fork leg and damping in the right fork leg.
As fork springs are no longer required, a significant weight advantage is achieved when compared to conven-
tional forks. The response on slightly uneven surfaces is significantly improved.
In normal driving mode, suspension 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
preference 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 adjustment is located at the upper end of the right fork leg.
The compression adjuster is located at the lower end of the right fork leg.
