The Ohlins BM525 STX 46 Adventure rear shock is built for BMW R 1150 RT riders who want consistent damping control across changing road conditions and touring loads. It uses a monotube design aimed at maintaining stability and chassis support over long distances. Setup changes are made via external adjusters, allowing you to tune feel without disassembly.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on predictable damping behaviour and repeatable adjustability. The BM525 is intended to improve control and comfort while preserving clear feedback at the rear wheel.

Shock design & features

This is an STX 46 Adventure-series rear mono shock with a gas-separated internal layout (not an emulsion design). The architecture is aimed at stable damping performance during extended use, including when the bike is carrying extra weight.

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment
  • Spring preload adjustment

Base setup (factory preset)

The shock is supplied with a factory baseline setting to suit the standard fitted spring. From there, you can refine preload for load and ride height, then use rebound and compression adjustments to balance comfort and control for your typical roads and touring conditions.

Before you install

  • Confirm fitment for BMW R 1150 RT and rear mono application before installation.
  • Check clearance around the shock body and adjusters, especially if you run luggage systems.
  • After installation, set sag and verify full range of adjuster movement.

Serviceability/lifecycle

Like other Ohlins units, this shock is designed to be serviced to maintain performance over time. Periodic inspection and servicing helps keep damping consistent, particularly for high-kilometre touring use.
