Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on damping control, heat management and repeatable setup changes. The STX Adventure range is intended for real-world riding conditions where grip, stability and rider comfort matter over long days.

Who this shock is for

• BMW R 1150 GS Adventure riders doing adventure touring on sealed and unsealed roads
• Riders carrying luggage or regularly riding two-up who want steadier chassis control
• Anyone wanting a serviceable aftermarket rear shock with external adjustments

Shock design & features

This is an STX 46 rear mono shock with an oil/gas separated internal architecture for consistent damping during sustained use. The design is aimed at keeping damping behaviour stable when conditions change, such as long rough sections or when load and pace vary.

Tuning controls

The BM215 provides external rebound damping adjustment and compression damping adjustment so you can tune how the shock returns after bumps and how it resists compression over impacts and undulations. It also includes spring preload adjustment to suit rider weight and additional load from luggage or a pillion.

Before you install

• Confirm all mounting hardware and clearances during installation on the rear mono position.
• Set sag with the correct preload for your typical load, then fine-tune rebound and compression damping from there.
• If you frequently switch between solo and loaded riding, note your preferred settings so you can return to a known baseline.

Serviceability/lifecycle

Ohlins shocks are designed to be maintained and serviced to keep performance consistent over time. Routine servicing helps refresh oil and seals, and allows inspection of wear items to support long-term reliability.
