Set: Performance Shock Absorbers, Red-Black with ABE, 360mm - for S50, S51, S70 Enduro ZT-Tuning Performance Shock Absorber Set with Hydraulic Damping The next stage of development on the way to the perfect chassis. Already with the optimized series shock absorbers, we were able to make a very big step in improving the Simson chassis. With the new Performance Shock Absorbers, we can raise the bar even higher. In addition to the visually appealing design, we have specially adapted the spring and damping for the S51 chassis. Most shock absorber sets have very poor or no damping properties at all, i.e., the compression and rebound occur almost unbraked/undamped. The result is very restless driving behavior with aftershocks. With our shock absorbers, we have carefully adjusted both the rebound and compression damping to achieve balanced driving behavior. This enables high driving comfort and equally high driving stability at higher speeds. - Including ABE for download (General Operating Permit) for the Simson types S50, S51, S53, S70, and S83, therefore Plug & Play LEGAL for use on public roads - Shock absorber length adjustable by thread (Note: ABE only applies to the variant with 360mm adapter piece) - Diameter of mounting bushings 8 mm (without annoying reducing sleeves) - Spring preload infinitely adjustable by thread - Progressive spring winding for best response and spring rate - Optimized rebound and compression stage for high driving stability Note Please note that body washers with a sufficiently large diameter must be used here. This is also necessary for the series Enduro shock absorbers. This prevents slipping out or twisting.
