shock absorber type 641 Competition

Our suspension conversion realises a better response behaviour of the fork.
This is achieved by replacing the linear fork springs with progressive fork springs. The second spring rate provides a larger reserve.
The standard shock absorber has a relatively high rebound damping, so we have slightly increased the spring rate and adjusted the rebound and compression damping. This also adjusted the suspension geometry of the front and rear axle via the negative spring travel.
Our conversion also offers a significantly larger range of adjustment than the series.

With this shock absorber the compression tank is connected to the shocks´ body by a flexible steel hose. Therefore it is an ideal alternative for road motorcycles with limited space. The hose can be placed individually where there is enough space for example on the rear frame where air flow can provide additional cooling. The adjustment screws for high- and low-speed compression, each tunable in 22 clicks, can be easily reached from the outside. Rebound can be modified by an open bleed system in 22 clicks and the preload is continuously adjustable.
