The Ohlins BM507 STX 36 Adventure is a rear shock absorber designed for BMW K 1200 GT and K 1200 RS applications. Built around Ohlins’ proven STX architecture, it focuses on controlled damping and consistent feel over varied road surfaces. It’s intended for riders who want a more tuneable suspension solution for touring and mixed-condition use.

Ohlins | Made to race, perfected to ride

Ohlins suspension units are developed with an engineering-first approach to damping control and long-term serviceability. The BM507 is part of the STX 36 Adventure family, aimed at improving stability and comfort when conditions and loads change. As a purpose-built rear unit, it targets traction and composure at the back of the motorcycle.

Who this shock is for

This rear mono shock suits riders using their K 1200 GT or K 1200 RS for touring and extended road kilometres where ride quality and chassis control matter. It’s also relevant if you want adjustability to better match your bike to different riding conditions. If your current rear suspension feels inconsistent or difficult to balance front-to-rear, a dedicated aftermarket unit can help with setup flexibility.

Shock design & features

The BM507 is an STX 36 Adventure rear shock using an emulsion design, where oil and gas are within the same main body. This layout is compact and widely used in performance rear shocks, with Ohlins focusing on damping consistency and predictable response. The unit is supplied with an Ohlins spring (00180-58).

Tuning controls

This model includes rebound damping adjustment, allowing you to fine-tune how quickly the rear shock extends after compression. Rebound tuning is typically used to manage stability over undulations and to keep the rear tyre loaded more consistently. Adjustment can be used to suit changes in riding pace and general road conditions.

Before you install

Confirm compatibility with BMW K 1200 GT and K 1200 RS, and check surrounding clearance and mounting hardware condition during installation. After fitment, set sag and verify rebound adjustment range from a known baseline so changes are repeatable. If you regularly carry luggage or a pillion, plan your setup around your most common load.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced to maintain damping performance over time. Periodic inspection and servicing helps keep oil condition and internal wear under control, especially for bikes used for long-distance riding. A maintained unit will generally deliver more consistent behaviour than a sealed, non-serviceable alternative.
