Description
Information

The Ohlins KA504 STX 36 Twin shock is a rear twin-shock upgrade for the Kawasaki ZRX 400. Built around Ohlins’ STX architecture, it’s designed to deliver consistent damping control and clear chassis feedback across varied road conditions. This unit suits riders who want a more controlled, tuneable rear end without compromising everyday ride quality.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on stability, traction and predictable damping behaviour. The KA504 is part of the STX 36 Twin family, aimed at modernising twin-shock performance while maintaining a classic layout.

Who this shock is for

ZRX 400 owners wanting improved rear-wheel control and stability from a twin-shock setup
Riders who value damping consistency during longer or harder rides
Anyone looking for a quality suspension foundation to match tyres and riding style

Shock design & features

This is a gas-pressurised rear twin-shock design intended to help maintain damping consistency in demanding use. As an STX unit, it’s engineered for controlled response and improved traction compared with basic twin-shock arrangements.

Tuning controls

The KA504 provides adjustable compression and rebound damping, allowing you to tailor the response for road conditions, load and riding pace. These controls are intended to help balance comfort, grip and stability as your setup evolves.

Base setup (factory preset)

This shock is supplied with an Ohlins factory baseline to provide a solid starting point. Fine-tuning should be completed after confirming sag and overall chassis balance with your rider weight and typical load.

Before you install

Confirm shock length and stroke suitability for your motorcycle and intended ride height
Inspect linkage/bushings and mounting hardware condition before fitment
Plan to set rider sag and then adjust damping based on real-world feedback
