The Ohlins BM552 STX 46 Adventure rear shock is designed for adventure and touring use where control and comfort matter over mixed surfaces. Built to suit the BMW R 1200 GS rear mono position, it supports consistent chassis behaviour when conditions change. The focus is predictable damping and stability for longer days in the saddle.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a strong engineering focus on damping control and ride consistency. This unit is part of the STX 46 Adventure family, aimed at riders who want confidence and composure on rough roads and tracks. It is intended as a complete rear shock replacement.

Shock design & features

This is a monotube shock with a separated gas and oil design via a remote reservoir, helping maintain damping consistency as conditions and heat load vary. The architecture supports stable performance over repeated bumps and long-distance riding. It is configured for rear mono fitment.

Tuning controls

Adjustment is provided for rebound damping and compression damping, allowing you to tailor shock response to terrain and riding style. Spring preload adjustment is also included to help set ride height and balance when carrying different loads. These controls are intended to make practical setup changes without disassembly.

Base setup (factory preset)

The shock is supplied with an Ohlins baseline setting intended as a starting point for the target motorcycle. From there, fine-tuning typically focuses on achieving correct sag with preload, then balancing rebound and compression for grip and support. Small, methodical changes are recommended so you can feel the effect of each adjustment.

Before you install

• Confirm the application and fitment for BMW R 1200 GS rear mono position before installation.
• Inspect linkage, bearings, and mounting hardware for wear so the new shock can work as intended.
• After installation, set preload for your typical riding load, then tune damping to suit your surfaces.

Serviceability/lifecycle

As a rebuildable Ohlins unit with separated gas and oil, this shock is intended to be serviced to maintain performance over time. Regular inspection and periodic servicing help keep damping consistent, particularly for frequent off-road use or extended touring.
