The Ohlins YA443 STX 36 Twin shock is a rear suspension upgrade designed for the Yamaha SR 400. Built around Ohlins twin-shock architecture, it focuses on consistent damping control and clear chassis feedback on the road. The design uses a gas-pressurised damper to help maintain stable performance as conditions change.

Ohlins | Made to race, perfected to ride

Ohlins street shocks are developed using the same core damping principles found in competition products, then refined for real-world riding. The aim is predictable grip, stability and control rather than a harsh ride.

Who this shock is for

  • SR 400 riders wanting more controlled rear support and improved stability over varied road surfaces
  • Riders who value tunability to suit riding style, load, and tyre choices
  • Owners upgrading ageing or tired rear shocks to restore consistent damping behaviour

Shock design & features

  • STX 36 Twin rear shock configuration for twin-shock applications
  • Gas-pressurised damping system to help reduce fade and keep damping consistent

Tuning controls

  • Rebound damping adjustment

Before you install

  • Confirm fitment for Yamaha SR 400 and twin rear shock mounting prior to installation
  • Set sag and check clearances after installation, then fine-tune rebound to match your roads and load

Serviceability/lifecycle

Like all performance dampers, periodic servicing helps maintain damping consistency and seal life. Keeping the unit clean and inspecting for leaks or damage will support long-term performance.
