Shock absorber springs for Yamaha XJ 900

The shock absorber springs from the PROGRESSIVE SUSPENSION brand have been specially developed for the Yamaha XJ 900. These springs belong to the 12-Series and are designed for rear suspension. They are characterized by a simple progressive spring rate, which offers graduated spring hardness and thus enables optimized damping.
