–
For optimal motorcycle riding characteristics and to avoid
damage to forks, shock absorbers, link fork and frame, the
basic settings of the suspension components must match the
rider's weight.
–
In the delivered condition, Husqvarna motorcycles are
adjusted for an average rider's weight (with full protective
clothing).
Guideline
Standard rider weight
–
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 adjusting
the spring pretension of the shock absorber, but in the case
of large weight differences, the springs must be replaced.
Air suspension WP Suspension AER 48 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 conventional 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 to the rider's
weight, surface conditions and the rider's preference using a fork
airpump. The fork does not have to be dismantled. The time con-
suming 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 sus-
pension 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.
