The Ohlins BM543 STX 46 Adventure rear shock is built to improve control and composure on a BMW R 1200 GS across sealed roads and demanding off-road surfaces. It is designed for riders who want a more consistent feel through long-distance touring, corrugations and rough climbs. As a dedicated rear mono shock, it targets stability, comfort and predictable grip when conditions and loads change.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on damping control and repeatable behaviour in real riding conditions. This unit is part of the STX Adventure family, aimed at the needs of big-bore adventure bikes that see mixed terrain and varying payloads.

Who this shock is for

• Adventure and touring riders seeking better stability over rough surfaces and long days in the saddle
• Owners who regularly ride with luggage and/or a pillion and want more controlled chassis behaviour
• Riders who value the ability to tune feel for changing terrain rather than a one-size setup

Shock design & features

This is an oil/gas separated rear shock design for more consistent damping under hard use compared with an emulsion layout. The STX architecture is intended to maintain damping control when heat and repeated impacts build during extended off-road riding. It is designed as a direct-fit rear replacement for the BMW R 1200 GS.

Tuning controls

The BM543 provides external adjustment for rebound damping and compression damping, along with hydraulic spring preload adjustment to suit load changes. These controls are intended to make it practical to tune ride feel for conditions such as corrugations, rocky sections, and highway touring with extra weight.

Before you install

• Confirm application suitability for your exact BMW R 1200 GS model and year before fitment
• Set preload for your typical riding load (solo, luggage, pillion) before fine-tuning damping
• Have installation carried out by a qualified technician and check fasteners and clearances after initial rides

Serviceability/lifecycle

Like all performance shocks, this unit is designed to be serviced to maintain consistent damping and seal life over time. Regular servicing based on use conditions (dust, water crossings, heavy off-road work) will help keep performance predictable and extend component life.
