The Ohlins BM424 STX 46 Adventure rear shock is built for BMW R 1100 GS and R 850 GS applications where stability and control matter over long distances. It is designed to support mixed-surface riding and varying loads while maintaining consistent damping behaviour. The STX architecture separates oil and gas to help manage heat and reduce fade in demanding conditions.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on controlled damping, predictable feedback and long-term serviceability. This unit is part of the STX 46 Adventure family, aimed at riders who want confidence on rough roads without compromising on-road composure.

Who this shock is for

  • Adventure and touring riders covering long days on sealed roads, gravel and corrugations
  • Riders who alternate between solo and loaded setups (luggage and/or pillion)
  • Owners wanting a rebuildable rear shock solution for their BMW

Shock design & features

This is an STX 46 rear mono shock with a separated oil/gas layout rather than an emulsion design. The goal is more consistent damping during sustained use, especially when the shock is working hard over uneven surfaces.

Tuning controls

The shock includes rebound damping adjustment and a remote hydraulic spring preload adjuster for quick load compensation. These external controls let you tune feel and ride height balance to suit terrain and changing luggage weight.

Before you install

  • Confirm fitment for BMW R 1100 GS and R 850 GS and check any model/year requirements before ordering
  • Set sag and preload for your typical riding load, then refine rebound damping based on traction and control
  • Inspect linkage and mounting hardware condition during installation

Serviceability/lifecycle

Ohlins shocks are designed to be serviced. Regular maintenance helps keep damping consistent and extends component life, particularly for frequent off-road or heavily loaded use.
