The Ohlins KA634 STX 46 Supersport rear shock absorber is built for Kawasaki GPZ 900 Racing applications where consistent damping control and clear chassis feedback matter. Based on Ohlins race-derived architecture, it supports stable behaviour under braking and predictable drive out of corners. The gas-pressurised layout is intended to maintain damping consistency during extended, demanding use.
