Function and area of application

These shock absorbers are designed for heavy-duty operation and significantly improve the suspension characteristics of the motorcycle. The progressive spring rate enables gentle response on small bumps and increasing hardness under heavier loads. The gas-filled damping prevents the suspension from bottoming out and increases driving stability even at higher speeds or on uneven terrain.

The automatic setting makes it easier to use as no manual intervention is necessary to adjust the damping. The internal reservoir contributes to a compact and robust design that protects the shock absorber from external influences.
