SHOWA CORPORATION | Product Information | Motorcycle: Shock Absorbers (Rear Cushion)

Functions and Roles

The rear cushion is a key structural component of a motorcycle, holding the rear wheel and providing the function as a shock absorber. With the linkage of the rear wheel and swing arm, this vital part demands excellent ability to closely follow road contours through smooth operation and steady damping force, while retaining high rigidity.
