The Ohlins YA604 STX 36 twin rear shock set is built for the Yamaha XJR 1300, focusing on controlled damping and consistent feel across a wide range of road conditions. As a matched pair for twin-shock fitments, it’s aimed at improving chassis stability and traction without making the ride unpredictable. This unit uses a gas-pressurised design to help maintain damping consistency during longer rides.

Ohlins | Made to race, perfected to ride

Developed from Ohlins race experience, the STX 36 Twin platform is designed to deliver predictable feedback and stable handling. It’s a practical performance upgrade for riders who want a more controlled rear end and clearer tyre contact feel.

Who this shock is for

Suited to XJR 1300 riders who want improved support, stability and confidence from the rear suspension. It’s also a strong option if you regularly carry load or ride a mix of smooth and rougher roads and want a shock that can be tuned to suit.

Shock design & features

This is a twin-shock rear configuration using a gas-pressurised, oil/gas-separated layout to help reduce fade and maintain consistent damping. The STX 36 architecture is intended to provide stable control under braking and acceleration while improving rear tyre contact over changing surfaces.

Tuning controls

The YA604 provides external damping adjustment for both compression and rebound, allowing you to balance ride comfort, stability and grip to suit your riding conditions. It also includes spring preload adjustment to set sag correctly for your weight and typical load.

Before you install

  • Set rider sag and static sag first, then fine-tune damping in small steps.
  • Confirm clearance around chain, exhaust and bodywork through full suspension travel.
  • If your bike has non-standard linkage geometry or ride height changes, re-check setup after installation.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced and reconditioned to maintain performance over time. Regular servicing helps keep damping consistent and allows internal wear items and fluid to be refreshed as needed.
