The Ohlins STX 46 Supersport rear shock for the Yamaha YZF 750 SP is built around a track-focused damping layout aimed at delivering consistent tyre contact and clear chassis feedback. It uses a monotube design with pressurised gas and a separate reservoir to keep damping stable as temperatures rise. This unit is intended for riders who want a more controlled rear end under braking, turn-in and drive.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing experience, the STX 46 Supersport platform focuses on predictable damping behaviour and repeatable adjustment. The goal is not to change the character of the bike, but to give you a more stable baseline you can tune for your riding and tyres.

Who this shock is for

Suited to riders using the YZF 750 SP for track days and fast road riding where higher corner speeds and harder braking demand more control from the rear suspension. It is also appropriate if you want a wider, more usable tuning range than a basic replacement shock.

Shock design & features

This is a rear mono shock with an STX 46 Supersport architecture. It is a gas-pressurised, oil/gas separated design using a remote reservoir to help manage heat and maintain damping consistency during extended sessions.

Tuning controls

External adjustment is provided for rebound damping and compression damping, allowing you to balance grip, support and stability for your circuit, tyre choice and riding style. The unit also includes length adjustment to help fine-tune rear ride height and chassis attitude.

Before you install

Check clearance for the reservoir hose routing and ensure all linkage and swingarm bearings are in good condition, as wear here can mask suspension improvements. After installation, confirm sag and re-check settings once the shock has bedded in with your typical tyres and usage.
