The Ohlins BM053 STX 46 Street rear shock is built for BMW R 100 and R 80 series models needing controlled, consistent damping for road use. It is a mono rear shock in the STX 46 family, designed to improve stability and chassis feedback without compromising everyday ride quality. This unit uses a gas-pressurised layout with separated oil and gas to help maintain damping consistency.

Ohlins | Made to race, perfected to ride

Ohlins street shocks draw on proven internal design practices to deliver predictable behaviour across changing road surfaces. The focus is on control, traction and repeatability, with adjustment range intended for real-world tuning rather than extreme set-ups.

Who this shock is for

Suited to riders who want a more composed rear end for spirited street riding and touring on classic BMW air-cooled models. If you value clearer feedback mid-corner and more stability under braking and acceleration, this type of rear mono shock is a practical upgrade path.

Shock design & features

This is an Ohlins STX 46 mono shock with a gas-pressurised, oil/gas separated design. The architecture is intended to keep damping behaviour consistent during extended riding by reducing aeration of the oil compared with simpler designs.

Tuning controls

The BM053 provides rebound damping adjustment. This allows you to fine-tune how quickly the shock returns after compression to better match spring behaviour, tyre choice, load and riding style.

Before you install

  • Confirm fitment for your exact BMW model and year within the R 100 RS/RT and R 80 RS/RT range.
  • Set sag and baseline damping after installation to suit rider weight and luggage/passenger use.
  • Inspect mounting hardware and bushes during installation and replace any worn components.

Serviceability/lifecycle

Ohlins shocks are designed to be serviceable, allowing oil and wear parts to be renewed as the shock ages. Periodic servicing helps maintain damping consistency and protects internal components from contamination and oil breakdown.
