The Ohlins YA157 STX 46 Supersport rear shock is built for Yamaha YZF R1 riders chasing consistent damping control and clear tyre feedback on road and track. Based on Ohlins racing development, it focuses on stability, grip and predictable chassis behaviour under load. A gas-pressurised design helps maintain damping consistency when the pace increases.

Ohlins | Made to race, perfected to ride

Developed from Ohlins competition know-how, the STX Supersport platform is aimed at riders who want a more controlled, confidence-inspiring rear end without losing feel. It is designed to work as a complete damping system rather than a cosmetic upgrade.

Who this shock is for

Suited to Yamaha YZF R1 owners who ride aggressively, do track days, or want more dependable rear grip and stability when braking hard and driving out of corners. It is also a good match if you are setting sag properly and want meaningful adjustment range for different tyres and conditions.

Shock design & features

This is a gas-pressurised rear mono shock with separated oil/gas to help reduce cavitation and maintain consistent damping behaviour. The STX Supersport layout is intended to deliver strong chassis support with good sensitivity, especially when the rear tyre is loaded during corner exit.

Tuning controls

The YA157 provides external damping adjustment for both compression and rebound, allowing you to balance support and grip to suit your riding style. This makes it easier to tune stability, traction feel and how quickly the shock recovers after bumps and kerb strikes.

Before you install

• Confirm spring preload and sag are set for your weight and intended use before making damping changes.
• Make one change at a time and record your baseline so you can return to a known setting.
• Inspect linkage bearings and mounting hardware condition, as worn components can mask suspension improvements.

Serviceability/lifecycle

As an Ohlins performance unit, this shock is designed to be serviced and reconditioned to maintain performance over time. Regular servicing is recommended if the bike sees frequent track use or harsh conditions.
