Ohlins | Made to race, perfected to ride

Developed from Ohlins racing suspension architecture, this shock focuses on predictable support, controlled weight transfer and repeatable setup changes. It is designed to integrate cleanly with the bike’s linkage and geometry for track-focused use.

Who this shock is for

  • Riders chasing dependable damping feel during track sessions and race practice
  • Owners who want a dedicated rear shock solution for the Kawasaki ZX-4RR / ZX4-R platform
  • Setups where precise chassis balance and traction management matter more than comfort bias

Shock design & features

This is a TTX (twin-tube) rear shock with oil and gas separated for consistent damping. The architecture supports stable pressure control and helps maintain damping performance through repeated hard use.

Tuning controls

The KA400 provides external damping adjustments for compression and rebound, plus ride height adjustment to help fine-tune chassis attitude. These controls allow structured changes to grip, support and turn-in behaviour without changing internal components.

Before you install

  • Confirm compatibility with your exact model and year within the ZX-4RR / ZX4-R range before fitting.
  • After installation, set sag and baseline damping with your current tyres and intended track pace in mind.
  • Use the recommended Ohlins oil specified for this unit when servicing.

Serviceability/lifecycle

This shock is fully serviceable and designed for routine inspection and rebuilds as part of a track maintenance schedule. Regular servicing helps keep damping consistency and seal life where it should be.
