Ohlins | Made to race, perfected to ride

Ohlins road and track shocks are engineered to offer stable chassis behaviour and clear feedback at the tyre. This model sits within Ohlins’ performance shock range for supersport-style fitments.

Who this shock is for

  • Riders upgrading from a worn or under-sprung OE rear shock
  • Track-day and sporty road riders chasing improved support and consistency
  • Owners wanting a serviceable shock with proper setup scope for their weight and tyres

Shock design & features

This is an STX 46 rear shock for rear mono fitment. It uses a sprung shock body and is supplied with an Ohlins spring already fitted, providing a known starting point for setup work.

Base setup (factory preset)

Ohlins shocks are delivered with a factory baseline intended to suit an average rider and typical road/track use. From there, final setup should be completed to match rider weight, tyres, riding pace and track/road conditions.

Before you install

  • Confirm correct fitment for your exact GSX-R 1000 model and year
  • Inspect linkage bearings and swingarm pivots and service as needed before fitting a new shock
  • After installation, set rider sag and re-check fasteners after the first ride

Serviceability/lifecycle

This Ohlins rear shock is designed to be maintained. Periodic servicing helps keep damping consistent and extends component life, particularly with regular track use.
