The Ohlins STX 46 Adventure rear shock for the BMW F 650 GS is built for riders who want consistent damping control across mixed surfaces and changing loads. It’s designed to keep the chassis settled when conditions get rough, while still maintaining a controlled, compliant feel on the road. External adjustments let you fine-tune behaviour to suit your route and setup.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on damping consistency, component quality, and service life. The STX architecture is a proven platform for adventure and touring use where heat management and stability matter over long days.

Who this shock is for

  • BMW F 650 GS riders mixing sealed roads with gravel, corrugations, and rougher tracks
  • Touring setups carrying luggage and/or a pillion where rear ride height and control can change
  • Riders wanting a serviceable upgrade with external tuning rather than a fixed OEM-style unit

Shock design & features

This is an Ohlins STX 46 rear mono shock with separated oil and gas to help maintain damping consistency as conditions and temperatures vary. It’s intended to improve control through repeated hits and long-distance riding by keeping the damping behaviour stable and predictable.

Tuning controls

External adjusters provide:

  • Rebound damping adjustment
  • Spring preload adjustment

These controls allow you to balance comfort, traction, and chassis stability for different surfaces and load configurations.

Serviceability / lifecycle

Like other Ohlins units, this shock is designed to be maintained rather than replaced. Periodic servicing helps keep damping performance consistent and extends component life, especially for adventure use where dust, water crossings, and sustained vibration are common.

Before you install

  • Confirm compatibility for your exact BMW F 650 GS model and year prior to fitment
  • Set sag and preload for your typical riding load before making damping changes
  • If you frequently change between solo and loaded touring, note your settings so you can return to a known baseline quickly
