The Ohlins BM940 STX 46 Adventure rear shock is designed for BMW R 1150 GS riders who want consistent control across mixed surfaces and varying loads. Built around Ohlins’ STX architecture, it focuses on predictable damping behaviour over long days on the road and rougher tracks. It’s a serviceable rear mono shock intended for adventure and touring use.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a strong engineering focus on damping control and repeatability. The BM940 is part of the STX 46 Adventure family, aimed at improving composure and stability without compromising ride comfort. It’s suited to riders who prioritise confident chassis behaviour in real-world conditions.

Who this shock is for

• BMW R 1150 GS owners riding adventure-touring routes that mix sealed and unsealed roads
• Riders carrying luggage or a pillion who want more consistent rear-end support
• Anyone looking for a rear shock that can be tuned to conditions rather than left fixed

Shock design & features

This is an Ohlins STX rear mono shock with oil and gas separated for more consistent damping during extended use. The design is intended to maintain stability and traction when the pace or surface changes. As a serviceable unit, it can be maintained over time to keep performance consistent.

Tuning controls

The BM940 includes external damping adjustment for rebound, letting you fine-tune how quickly the rear returns after bumps and load changes. It also includes spring preload adjustment to suit rider weight and luggage requirements. These adjustments are intended to be accessible for practical setup changes between riding conditions.

Before you install

• Confirm fitment for the BMW R 1150 GS and your current rear suspension configuration
• Set sag and preload for your typical riding load before adjusting rebound
• After installation, re-check fasteners and clearances through the full range of motion

Serviceability / lifecycle

Ohlins shocks are built to be serviced, supporting long-term ownership and consistent performance. Regular inspection and periodic servicing help maintain damping quality, especially for bikes used in dust, water crossings, or sustained rough-road conditions.
