The Ohlins YA323 STX 36 Twin shock set is a rear suspension upgrade designed to suit the Yamaha XJ 900. Built around Ohlins street and track development, it focuses on stable damping behaviour, predictable chassis response and consistent control. This unit is intended for riders who want a more composed rear end without losing ride quality.

Ohlins | Made to race, perfected to ride

Ohlins twin shocks are engineered to deliver repeatable damping performance and clear feedback through the tyre. The STX platform is designed to manage heat and load changes in real-world riding, helping the bike stay settled through braking, cornering and acceleration.

Who this shock is for

Suited to Yamaha XJ 900 owners chasing better control from the rear suspension for spirited road riding and occasional track use. It’s also a good fit if your current shocks feel underdamped, inconsistent over bumps, or struggle to maintain traction when the pace increases.

Shock design & features

This is an STX 36 Twin rear shock configuration, using two rear units. The damping system is gas-pressurised for consistent performance under sustained use, supporting stable damping and reduced fade compared with worn or basic OEM-style replacements.

Tuning controls

The YA323 provides external damping adjustments for both compression and rebound, allowing you to tune support and traction to suit tyres, load and riding style. Adjustability makes it easier to balance comfort and control without changing internal components.

Before you install

Confirm fitment for your exact model and any existing modifications. After installation, set sag and verify clearance through full suspension travel, especially if ride height, exhaust routing, or luggage systems differ from standard.
