The Ohlins YA509 STX 36 Twin rear shocks are built for the Yamaha XJR 400, delivering controlled, consistent damping for everyday road use and more spirited riding. This is a twin-shock rear arrangement designed to improve chassis stability and tyre contact through more accurate damping control. The architecture uses separated oil and gas for more stable performance during extended riding.

Ohlins | Made to race, perfected to ride

Developed from Ohlins suspension know-how, the STX 36 Twin range focuses on predictable response and clean feedback. The result is a rear end that is easier to read, making it simpler to load the tyre smoothly and keep the bike settled through changing conditions.

Who this shock is for

  • Riders restoring or improving an XJR 400 who want modern damping control in a twin-shock format
  • Street riders chasing better stability and traction without making the bike harsh or nervous
  • Owners who value adjustability for different roads, loads, and riding styles

Shock design & features

  • Twin rear shock configuration suited to the XJR 400 chassis layout
  • STX 36 Twin design with separated oil and gas to maintain damping consistency
  • Built to provide clearer feel from the rear tyre and more composed chassis behaviour

Before you install

  • Confirm fitment for your exact Yamaha XJR 400 model and year

Serviceability/lifecycle

These Ohlins units are designed to be serviced so damping performance can be maintained over time. Periodic servicing helps keep oil condition, seals, and internal wear in check, especially if the bike sees frequent use on rough roads.
