The Ohlins KA789 TTX RT rear shock is a dedicated replacement unit for the Kawasaki ZX-6R, built around Ohlins’ twin-tube damping architecture to deliver consistent control under hard use. It’s designed to give clearer chassis feedback and a wider, more usable tuning range than a standard shock. As a gas-separated design, it helps maintain damping stability as temperatures rise.

Ohlins | Made to race, perfected to ride

This shock comes from Ohlins’ track-focused development, with a layout intended to keep damping behaviour stable and predictable. The aim is repeatable feel and traction through braking, turn-in and drive.

Who this shock is for

Suited to riders using the ZX-6R for track days, supersport racing, or fast road riding where tyre grip and chassis balance matter. It’s also a good fit if you want more precise adjustment and feedback when changing tyres, geometry or ride heights.

Shock design & features

The TTX RT platform uses a twin-tube damper arrangement with oil and gas separation to reduce aeration and help resist fade. The internal flow paths are designed to provide controlled damping response and maintain composure when the bike is loaded up in high-demand conditions.

Tuning controls

The KA789 provides external adjustment for rebound damping and compression damping. These controls are intended to let you tailor grip, support and response to suit track surface, tyre choice and rider preference.

Before you install

  • Confirm compatibility with your exact ZX-6R model and year before fitting.
  • Check clearance, hose/routing (if applicable), and that all mounting hardware is in good condition.
  • For best results, set sag and baseline damping with the shock installed and the bike at operating condition.
