The Ohlins YA155 STX 46 Supersport rear shock absorber is built for Yamaha YZF R1 riders chasing predictable damping control and clear chassis feedback. Developed from Ohlins road-race experience, it focuses on traction, stability and repeatability under hard riding. This unit uses a gas-pressurised damping system to help maintain consistency as temperatures and loads change.

Ohlins | Made to race, perfected to ride

STX 46 Supersport is a performance-focused rear mono shock platform designed for fast road and track use. It’s intended to give the rider a more controlled rear contact patch and improved confidence when pushing braking and corner-exit loads.

Who this shock is for

  • YZF R1 owners upgrading from OEM suspension for sharper feel and stability
  • Riders who want broader tuning range for trackdays or aggressive road riding
  • Anyone needing more consistent damping behaviour from a gas-pressurised design

Shock design & features

  • Rear mono shock for Yamaha YZF R1 fitment
  • Gas-pressurised damping system designed to maintain stable damping performance
  • Race-developed valving approach aimed at improving grip and chassis control

Tuning controls

  • Rebound damping adjustment for controlling return speed and stability on corner exit
  • Compression damping adjustment for support under braking and load transfer
  • Length adjustment to fine-tune rear ride height and chassis balance

Before you install

  • Confirm your exact YZF R1 model and year compatibility before fitting
  • Plan a baseline setup check after installation (sag and damping balance) to match your weight and tyres
  • For best results, have installation and initial setup carried out by an experienced suspension technician

Serviceability/lifecycle

As an Ohlins performance shock, the YA155 is designed to be serviced and revalved when required. Regular inspection and periodic servicing help maintain damping quality, consistency and seal life, particularly with frequent track use.
