Shock Absorber Type 641 Competition

As standard, the fork has a very soft spring. The Wilbers solution uses slightly harder, progressive springs. On the rear shock, the spring rate is adjusted via a slightly harder spring, in combination with optimised rebound and compression damping. The suspension geometry on the front and rear axle is sensibly adjusted via the negative spring travel. Originally, the vehicle has very high negative spring deflections. These are adjusted by a slightly shorter suspension strut, so that the original seat height is maintained. This results in a better ride and better handling, which also contributes to a safer ride. 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.
