The Ohlins YA138 STX 36 Twin is a rear twin-shock unit for the Yamaha XJR 400, built around Ohlins’ proven street performance architecture. It uses a pressurised, separated oil/gas design to maintain consistent damping through changing conditions. This unit includes external adjustments to help you tailor ride support and control to your bike and load.

Ohlins | Made to race, perfected to ride

Who this shock is for
