The Ohlins YA607 STX 46 Supersport rear shock is built for Yamaha TZ 250 riders who need consistent damping control and clear chassis feedback in demanding track use. Developed from race-derived suspension architecture, it focuses on stability, traction and predictability when the pace rises. The gas-pressurised layout helps maintain damping consistency during extended sessions.

Ohlins | Made to race, perfected to ride

Ohlins Supersport shocks are designed around track-focused damping control and repeatable adjustment. The aim is to deliver a stable platform that communicates grip changes clearly, so you can tune for conditions and riding style without losing consistency.

Who this shock is for

  • Track and race riders chasing improved stability under braking and better control through fast direction changes
  • Riders who want sharper chassis feedback to support confident corner entry and exit
  • Owners looking for a dedicated rear mono shock solution for Yamaha TZ 250 fitment

Shock design & features

This is a gas-pressurised, oil/gas separated shock design intended to reduce fade and keep damping behaviour consistent when the shock is working hard. It uses dedicated damping circuits to support controlled wheel movement and maintain traction through cornering loads.

Tuning controls

Adjustment is provided for both compression damping and rebound damping. This allows you to balance support versus compliance for corner entry, mid-corner stability and drive, while managing how quickly the rear returns after bumps and load transitions.

Before you install

  • Confirm spring rate and fitment details match your current setup and intended use
  • Set sag and baseline damping before making finer changes, then adjust in small steps and test
  • Use the recommended Ohlins shock oil when servicing to maintain intended damping performance
