Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on stable damping performance and reliable adjustment for real-world riding conditions. The STX Adventure family is aimed at riders who mix sealed and unsealed roads and want a more controlled, less fatiguing ride over long distances.

Who this shock is for

  • Riders using their BMW R-series for touring, commuting and light adventure duty
  • Owners carrying luggage or a pillion who want steadier ride height and control
  • Those chasing improved composure over rougher surfaces without sacrificing comfort

Shock design & features

This is an Ohlins STX 46 Adventure rear shock for twin-shock fitment. It uses a separated oil/gas design to help maintain damping consistency as conditions and temperatures change, and is intended to deliver controlled movement through repeated bumps and corrugations.

Tuning controls

This shock includes external adjustment to support practical, on-bike tuning for changing loads and road conditions. Use the adjusters to balance comfort, control and stability to suit your bike setup and riding environment.

Before you install

  • Confirm fitment for your exact BMW model and year, and that your bike uses a twin rear shock arrangement
  • Inspect mounting hardware and bushes, replacing worn components during installation
  • After installation, re-check fasteners and alignment once the suspension has settled

Serviceability / lifecycle

Ohlins shocks are serviceable and can be maintained to keep performance consistent over time. Regular inspection and periodic servicing will help preserve damping quality, especially for bikes used on rough roads and long trips.
