The Ohlins STX 46 Supersport rear shock for Yamaha TZ 250 is built around race-derived damping control for consistent feel and feedback. The monotube design uses separated oil and gas to help maintain damping consistency through hard use. It’s intended for riders who want a suspension unit that can be tuned precisely to suit track conditions and riding style.

Ohlins | Made to race, perfected to ride

Developed from Ohlins circuit experience, this rear mono shock focuses on predictable chassis response under braking, through mid-corner, and on corner exit. The Supersport format prioritises damping control and repeatability for competitive track riding.

Who this shock is for

Suited to Yamaha TZ 250 riders setting the bike up for track use where grip, stability and clear feedback matter. It’s a sensible choice when you need a dedicated rear shock designed for consistent damping performance and adjustability.

Shock design & features

This is a gas-pressurised monotube shock with oil and gas separated to reduce cavitation and help keep damping stable. The STX architecture is designed to deliver controlled movement and good tyre contact during fast load changes typical of supersport riding.

Tuning controls

Adjustment is provided for rebound and compression damping, allowing you to balance support, grip and response. These controls are intended to let you fine-tune the rear of the bike for different track surfaces, temperatures and rider preferences.

Before you install

  • Confirm fitment for your Yamaha TZ 250 and check general condition of linkage, bearings and mounting hardware.
  • Record your current settings and ride height so changes can be evaluated methodically after installation.
  • After installation, re-check fasteners and verify smooth suspension movement through the full range.

Serviceability/lifecycle

Like all track-focused shocks, performance depends on oil condition and internal wear. Regular servicing helps maintain damping consistency and keeps adjustments working as intended over time.
