The Ohlins STX 46 Adventure rear shock for BMW R 1100 GS, R 1150 GS and R 850 GS is built for riders who want controlled suspension behaviour across changing surfaces and loads. It’s designed to maintain support and traction when conditions get rough, while keeping the bike predictable over long days. As an STX design, it uses a separated oil/gas layout to help deliver consistent damping.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on damping control, stability and repeatability. The STX platform is intended to provide a broad working range so you can tune feel without compromising composure. It’s a proven approach for adventure and touring applications where conditions vary constantly.

Who this shock is for

  • BMW GS riders mixing sealed roads, gravel and rougher tracks.
  • Touring riders carrying luggage or varying load from trip to trip.
  • Owners wanting a serviceable rear shock with proper adjustment range for real-world tuning.

Shock design & features

This is a mono rear shock in the Ohlins STX 46 Adventure family. The internal architecture separates oil and gas to reduce aeration and maintain damping consistency as the shock works through repeated impacts. It’s intended to provide stable chassis behaviour and clear feedback when grip and terrain change.

Tuning controls

Adjustment is provided for rebound damping. Spring preload can also be set to suit rider weight and load, helping maintain ride height and balance. These controls let you tune how quickly the shock extends after a bump and how the bike sits under acceleration, braking and luggage weight.

Before you install

  • Confirm fitment for BMW R 1100 GS, R 1150 GS and R 850 GS, and check the shock’s mounting position is rear.
  • After installation, set sag and then fine-tune rebound damping to match your tyres, surfaces and load.
  • Plan periodic servicing to keep performance consistent over time.
