The Ohlins BM689 STX 46 Street rear shock is built to deliver controlled damping and clear chassis feedback for road riding. Developed from Ohlins suspension know-how, it’s designed as a direct-fit rear mono shock for the BMW Megamoto. The STX architecture helps maintain consistent damping behaviour across a wide range of conditions.

Ohlins | Made to race, perfected to ride

Ohlins street suspension focuses on predictable support, grip and ride quality. This unit is part of the STX 46 Street family and is intended for riders who value stability and tunability without compromising everyday usability.

Shock design & features

  • STX-style rear mono shock design for the BMW Megamoto
  • Oil and gas separated damping system to help reduce aeration and maintain consistency
  • Purpose-built fitment to suit the motorcycle’s linkage and mounting layout

Tuning controls

This shock provides external adjustment for rebound damping and compression damping, allowing you to tailor support and control to your tyres, load and preferred feel.

Base setup (factory preset)

The shock is supplied with an Ohlins baseline setting intended as a starting point for street use. From there, adjust in small steps to match your road conditions and riding style.

Before you install

  • Confirm correct model fitment for your BMW Megamoto and check clearance at full suspension travel.
  • Inspect mounting hardware and bearings/bushes and replace any worn parts during installation.
  • After installation, set sag and then fine-tune damping to suit your usual riding conditions.

Serviceability/lifecycle

As with other Ohlins units, this shock is designed to be maintained and serviced over its life. Regular servicing helps keep damping performance consistent and protects internal components from wear and contamination.
