The Ohlins KA721 STX 46 Supersport rear shock is built for Kawasaki ZX-7R riders who want more control and clearer feedback from the rear tyre. Developed from race-derived suspension practice, it focuses on stability under load and consistent damping over a session. This unit uses a gas-pressurised damping system to help reduce fade and maintain repeatable behaviour.

Ohlins | Made to race, perfected to ride

Ohlins Supersport shocks are designed to deliver precise chassis control and predictable grip, especially when braking hard and driving out of corners. The KA721 is a dedicated fitment for the ZX-7R, intended as a direct-performance upgrade to the stock rear suspension.

Who this shock is for

Suited to riders who do track days, spirited road riding, or are chasing more consistent handling as pace increases. It is also a practical choice if you want a broader tuning window than an OE shock can provide.

Shock design & features

  • STX 46 Supersport architecture
  • Gas-pressurised damping system for consistent performance
  • High-speed response characteristics aimed at improving chassis control
  • Valving developed with race use in mind to support traction and stability

Tuning controls

This shock provides external damping adjustment for both compression and rebound, allowing you to tune support under load and manage how quickly the rear returns after bumps, braking, and corner exit drive.

Before you install

Set static and rider sag, then confirm linkage condition and bearings before fitting. After installation, start by evaluating rebound control and drive grip, then refine compression to balance support and compliance.

Serviceability/lifecycle

Like all high-performance shocks, periodic servicing helps keep damping consistent and protects internal wear parts. Regular inspection and oil/gas refresh are recommended as use and operating conditions accumulate.
