The Ohlins KA505 STX 36 is a rear twin-shock unit designed for the Kawasaki ZRX 400. Built around Ohlins’ street and track suspension know-how, it focuses on controlled damping and stable chassis behaviour. The design is intended to deliver consistent feel across a range of road conditions without relying on vague “one size fits all” settings.

Ohlins | Made to race, perfected to ride

Ohlins twin-shock rear suspension is developed to improve traction, stability and feedback. This unit suits riders chasing a more composed rear end under braking, corner entry and drive out of turns.

Who this shock is for

  • Riders upgrading from ageing or underdamped OEM twin shocks
  • Street riders who want improved control and ride quality with proper damping support
  • Sport-oriented riding where chassis feedback and stability matter

Shock design & features

  • STX 36 twin-shock rear configuration for twin-shock chassis layouts
  • Gas-pressurised damping design to help maintain consistent damping behaviour during use
  • Valving architecture aimed at predictable grip and chassis control

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment

Before you install

  • Confirm fitment for your Kawasaki ZRX 400 and check mounting hardware condition before installation
  • Set sag and balance front-to-rear after installation to make the most of the damping adjusters
  • If your bike has non-standard linkage or rear ride height changes, allow extra time for setup

Serviceability/lifecycle

Ohlins shocks are designed to be serviced to restore performance as oil and wear parts age. Regular inspection and periodic servicing helps keep damping consistent and protects internal components over the long term.
