The Ohlins KA803 STX 46 Supersport rear shock is built to provide controlled damping and clearer chassis feedback for the Kawasaki ZX-9R. It is a gas-pressurised design that helps maintain consistent performance as conditions and temperatures change. Developed from Ohlins race-derived architecture, it’s intended for riders who want a more tunable and stable rear end without compromising feel.

Ohlins | Made to race, perfected to ride

Ohlins suspension focuses on predictable damping behaviour and strong adjustability so the bike can be set up to suit the rider, tyres and surface. The STX Supersport platform is aimed at performance road and track-day use where repeatability and support matter.

Who this shock is for

  • Riders chasing improved rear-end control for spirited road riding.
  • Track-day riders wanting more stability and tuning range than a standard shock.
  • Owners who value consistent damping feel from session to session.

Shock design & features

This is an STX 46 Supersport rear mono shock with gas pressurisation to support the damping system under load. The internal layout is designed to deliver stable, controlled damping behaviour and clearer traction feedback from the rear tyre.

Tuning controls

The KA803 provides external adjustment for rebound damping and compression damping, along with a length adjustment to help fine-tune chassis attitude. This combination allows you to balance support, grip and stability to match your riding and setup goals.

Before you install

  • Confirm fitment for your exact Kawasaki ZX-9R model/year and any linkage or ride-height constraints.
  • Set sag and geometry after installation, then adjust rebound and compression in small steps to suit your tyres and surface.
  • Inspect bearings and linkage condition during installation so the shock can work as intended.

Serviceability/lifecycle

Ohlins shocks are built to be serviced and reconditioned as part of normal maintenance. Periodic servicing helps maintain damping consistency and extends component life, particularly when used on track or in demanding conditions.
