The Ohlins YA204 STX 46 Supersport rear shock is built to give Yamaha YZF R1 riders predictable damping control and clear chassis feedback in demanding road and track use. The design uses a gas-charged layout to help maintain damping consistency as temperatures and workloads rise. It is intended for riders who want a suspension unit that responds accurately to setup changes.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing experience, this Supersport-spec shock focuses on stability, traction and repeatability. It is designed to support confident corner entry and drive while keeping the bike composed under hard load changes.

Who this shock is for

  • YZF R1 riders upgrading from a standard rear shock for more controlled damping response
  • Trackday and supersport riders who want clearer feedback and consistency under aggressive riding
  • Owners who prefer a shock that can be tuned rather than ridden “as is”

Shock design & features

This is a gas-pressurised, oil/gas separated rear mono shock designed to resist fade and maintain stable damping performance. The STX architecture is aimed at delivering controlled traction and stability through fast direction changes, braking zones and acceleration loads.

Tuning controls

The YA204 provides external adjustment for rebound damping and compression damping, along with length adjustment to help fine-tune rear ride height and chassis attitude. These controls allow the shock to be matched to tyres, track grip, rider preference and overall balance.

Before you install

  • Set sag and balance front-to-rear before making damping changes
  • Make one change at a time and record what you did and how it felt
  • Check clearance and routing around the shock after installation, especially if other parts have been modified

Serviceability/lifecycle

This Ohlins unit is designed to be serviced and reconditioned over its life. Regular servicing helps keep damping performance consistent and ensures adjustments remain meaningful as the oil and seals age.
