Checking the basic chassis setting with rider's weight

Info

When adjusting the basic chassis setting, first adjust the shock absorber and then the fork.

Air suspension XACT 5543

Air suspension WP Suspension XACT 5543 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 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.

–

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.

–

This vehicle is delivered pre-set for a standard 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 preload, but in the case of large weight differences, the

springs must be replaced.
