Adjustline 641
With this shock absorber, the balance tank is mounted on a braided steel hose. This makes it an ideal alternative for streetnmotorcycles with space issues. The flexible hose allows the balance tank to be mounted where space is available – e.g., on the frame rear, where air currents from the air stream provide cooling. The adjustment knobs for the low- and high-speed range of the compression damping, each adjustable in 22 steps, are also easily accessible from the outside. The rebound can be adjusted 22-fold via an open bleed system, and the spring preload can be continuously adjusted.

Originally, the fork of the Harley Davidson Pan America has linear fork springs. These are replaced by us with progressive fork springs, which initially leads to significantly improved response and offers more reserve in the second spring rate than the standard setup.
On the rear shock absorber, the spring rate is adapted via a slightly harder spring in conjunction with optimised rebound and compression damping damping.
The chassis geometry on the front and rear axles has been sensibly adjusted via the negative spring travel. Originally, the vehicle has somewhat high negative spring travel. These have been compensated for by a minimally shorter shock absorber, so that the original seat height is maintained.
This results in improved riding behaviour and better handling, which also contributes to safer riding.
