The Ohlins SU143 STX 36 twin rear shock set is built for classic Suzuki GS and GSX models that benefit from modern damping control while retaining a twin-shock layout. It’s designed to improve chassis stability and traction through more consistent damping behaviour across varied road conditions. As an Ohlins unit, it focuses on predictable feel and tunability rather than changing the character of the bike.

Ohlins | Made to race, perfected to ride

Developed from Ohlins motorsport experience, the STX 36 Twin platform is intended for riders who want clearer feedback and better control from the rear end. The aim is stable, confidence-inspiring behaviour under braking, cornering, and acceleration.

Shock design & features

This is a twin-shock rear arrangement using a gas-pressurised damping system to help maintain consistent performance as conditions and temperatures change. The architecture supports stable damping response and improved rear tyre contact over bumps and during load transfer.

Tuning controls

This unit provides external damping adjustment for both compression and rebound, allowing you to tune support, comfort, and grip to suit your riding style and typical roads. Independent circuits help make changes more predictable when chasing a balanced setup.

Who this shock is for

Suited to riders restoring or updating a GS/GSX who want a quality rear suspension solution with meaningful adjustability. It’s also a good fit for riders who regularly ride briskly and want improved stability and traction without moving away from the original twin-shock format.

Before you install

Confirm compatibility for your exact model and year, and inspect linkage points, mounting hardware, and swingarm condition before fitting. For best results, set sag and baseline damping after installation so the adjusters are working within a useful range.
