Adjustline 641
With this shock absorber, the balance tank is attached to a braided steel hose. This makes it the ideal alternative for street motorcycles with space issues. The flexible hose allows the balance tank to be mounted where space is available – for example, at the frame rear, where air currents from the air stream provide cooling. The adjustment knobs for the low- and high-speed compression damping range, 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 base can be continuously adjusted.

Originally, the fork of the Harley Davidson Pan America has linear fork springs. These are replaced with progressive fork springs by us, which initially leads to significantly improved responsiveness and offers more reserve in the second spring rate than the standard model.
On the rear shock absorber, the spring rate is adjusted 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 wheel travel. Originally, the vehicle has somewhat high negative wheel travel. These have been compensated for by a minimally shorter shock absorber, so that the original seat height is maintained. This results in improved ride characteristics and better handling, which additionally contributes to safer riding
