The Ohlins BM431 STX 46 Adventure rear shock is built for the BMW R 1150 GS and is intended for riders who want consistent control and comfort across mixed surfaces. It uses an oil/gas separated design to help maintain damping consistency as conditions and loads change. Adjustment is provided to tune the shock to your bike, riding style and terrain.

Ohlins | Made to race, perfected to ride

Ohlins suspension is designed with a focus on damping control, chassis balance and repeatable performance. The BM431 is part of the STX Adventure family for adventure and touring use where stability matters over long days.

Who this shock is for

  • BMW R 1150 GS riders covering a mix of sealed roads and unsealed tracks
  • Touring riders who want improved control with luggage and changing loads
  • Owners looking for a quality replacement rear mono shock

Shock design & features

This is a rear mono shock in the STX 46 Adventure range. The oil and gas are separated to support consistent damping behaviour when riding over rough surfaces and during longer stints where heat build-up can affect feel.

Tuning controls

The BM431 provides external damping adjustment for rebound and compression, plus a spring preload adjustment. These controls let you balance support, comfort and traction when conditions, pace or load change.

Before you install

  • Confirm fitment for BMW R 1150 GS and check existing linkage and mounting hardware condition
  • Set sag and preload for your typical load before fine-tuning rebound and compression
  • After installation, re-check all fasteners and clearances through suspension travel

Serviceability/lifecycle

Like all performance shocks, regular servicing helps keep damping performance consistent and internal wear in check. Service intervals depend on use, especially in dust, water crossings and sustained rough-road riding.
