The Ohlins KA964 STX 36 Blackline rear shock pair is designed for the Kawasaki ZRX 1200, combining classic appearance with modern damping control. This twin-shock setup is intended to improve stability and ride quality while keeping the bike’s character intact. It’s a serviceable, tuneable suspension unit suited to road use where consistent feel matters.

Ohlins | Made to race, perfected to ride

Built around Ohlins STX technology, this Blackline pair focuses on controlled damping and predictable feedback. The twin rear layout suits motorcycles that rely on two rear units for both support and chassis balance.

Who this shock is for

Suited to riders of the ZRX 1200 who want a more planted rear end and improved compliance over imperfect surfaces. Also a good fit for owners aiming for a high-quality suspension refresh on a street-focused, classic-styled machine.

Shock design & features

This is an oil and gas separated shock design to help maintain damping consistency in real-world riding. The STX 36 Blackline family is intended to deliver stable performance with a finish that matches classic and custom builds.

Tuning controls

  • Rebound damping adjustment to manage how quickly the shock extends after a bump or load change
  • Compression damping adjustment to control shock movement under bumps and weight transfer
  • Spring preload adjustment to set ride height and support for rider/load

Before you install

  • Confirm correct fitment for Kawasaki ZRX 1200 and that both units are installed as a matched pair
  • Set sag and preload first, then refine damping in small steps to suit tyres, load, and road conditions
  • If your bike has other chassis modifications, plan on a baseline check of geometry and clearances after installation

Serviceability/lifecycle

As an Ohlins unit, the shocks are designed to be serviced to maintain performance over time. Periodic inspection and servicing helps keep damping consistent and preserves internal components.
