The Ohlins BM745 is an STX 36 rear twin shock solution for BMW R 1200 C, R 1200 C Independent, and R 850 C models. Built for improved chassis control and consistent damping, it is aimed at riders who want more composure and feedback from the rear suspension. The design uses a gas-pressurised damping system to help maintain stability across varying road conditions.

Ohlins | Made to race, perfected to ride

Ohlins road shocks draw on proven damping architecture to deliver predictable response and a controlled ride. The focus is on stability, traction and a clear connection between tyre and road, without making the bike feel harsh.

Who this shock is for

This rear twin shock setup suits riders who want a more controlled feel than standard suspension, particularly when loading the bike with a passenger or luggage, or when riding briskly on uneven surfaces. It is also a sensible choice if your current shocks are worn and you want a serviceable replacement with tuning flexibility.

Shock design & features

This is a gas-pressurised shock design to help reduce damping fade during longer rides. It uses separate damping circuits to better manage suspension movement over a range of inputs and supports a stable rear end under braking and through corners.

Tuning controls

The BM745 provides external damping adjustment for both compression and rebound, allowing you to balance comfort, grip and chassis attitude to suit your riding style. With independent control over these damping functions, you can address support under load separately from how quickly the shock returns after a bump.

Before you install

Confirm fitment for your exact model variant and ensure all mounting hardware and bushings are in good condition. After installation, set sag and check for adequate clearance through full suspension travel, then fine-tune damping once tyre pressures and load are finalised.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced to maintain damping performance over time. Periodic servicing helps keep oil condition, seals and internal wear under control, which supports consistent feel and longevity.
