shock absorber type 644 WESA Dynamic

With the “Dynamic-ESA”-system, BMW has developed a very good and pioneering suspension, which is permanently adapting to the road´s surface and riding situation. With our WESA-Dynamic technology we offer the possibility to adjust this suspension system individually referring to your requirements. According to your (and the load´s) weight and to the riding purpose, the damping characteristics are individually adjusted. Furthermore wishes of raisings or lowerings can be satisfied by the appropriate length of the new shock absorber. So in the end of the production you will receive a totally tailored suspension. Afterwards the biker himself has the possibility to finetune the compression damping of the shock with the high- and lowspeed valves of the external reservoir. Referring to possible raisings or lowerings for your bike, check the menu below.

Note:
For linkage (incl.), with the original electronic the shock has to be sent in. The original preload adjuster is reused. An extra bracket for fixing the brake fluid reservoir on a new place is also supplied. For linkage (incl.), with the original electronic the shock has to be sent in.

When rebuilding the ESA to WESA the functionality of the ESA adjustments remains completely intact. When rebuilding the ESA to WESA the functionality of the ESA adjustments remains completely intact.
