The Ohlins BM503 STX 46 Street rear shock is a purpose-built replacement for BMW R 1200 RT applications where control and ride quality matter. Built around Ohlins road-going suspension know-how, it focuses on consistent damping and predictable chassis behaviour. This unit is designed for street and touring use, with practical adjustment to tailor feel to load and riding conditions.

Ohlins | Made to race, perfected to ride

Ohlins brings proven damping architecture into a road-focused package for riders who want clear feedback and stable handling. The STX 46 Street family is aimed at everyday riding and long-distance comfort without losing support when pace increases.

Who this shock is for

  • BMW R 1200 RT riders looking to refresh worn suspension with a higher-quality damper.
  • Touring and commuting riders who carry luggage or a passenger and want better control.
  • Riders who value adjustability to suit different roads and loads.

Shock design & features

This is a gas-charged, oil/gas-separated rear mono shock from the Ohlins STX 46 Street range. The separated gas design helps maintain damping consistency as conditions change, supporting stable behaviour over a wide range of road use.

Tuning controls

This shock provides rebound damping adjustment, allowing you to tune how quickly the rear recovers after bumps and weight transfer. Spring preload adjustment is used to set ride height and support for rider weight, luggage, and passenger load.

Before you install

  • Confirm fitment for BMW R 1200 RT and check any model-year or variant requirements before installation.
  • Set sag and preload first, then fine-tune rebound to suit your roads and riding style.
  • Inspect linkage bearings and mounting hardware condition during installation, as worn components can mask the benefits of a new shock.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced, with routine maintenance helping preserve damping quality and seal life over time. Periodic servicing is recommended, particularly for frequent touring or rough-road use.
