The Ohlins BM653 STX 46 Street rear shock is designed for BMW R nineT and R nineT Pure riders wanting more consistent damping control in everyday road use. Built around Ohlins’ STX architecture, it focuses on stability, grip and predictable chassis behaviour. This unit uses a gas-separated design to help maintain damping consistency as conditions change.

Ohlins | Made to race, perfected to ride

Ohlins street shocks are developed from the same engineering approach used in competition, then tuned for real-world road riding. The aim is controlled suspension movement and clear feedback, without making the bike feel harsh. For the R nineT platform, that translates to better support through corners and under braking.

Shock design & features

This is a rear mono shock from the Ohlins STX 46 Street family. The internal layout separates oil and gas to reduce aeration and help the damping stay consistent over longer rides. It is engineered as a complete replacement unit to work as an integrated part of the motorcycle’s rear suspension system.

Tuning controls

The BM653 provides external rebound damping adjustment to tailor how quickly the shock returns after compression. It also includes a spring preload adjuster to set ride height and sag for rider weight, passenger use, and luggage. These controls let you refine comfort and stability without changing core components.

Base setup (factory preset)

Ohlins supplies this shock with a baseline internal setting intended to suit typical road riding on the listed models. Preload and rebound adjustment are provided so you can fine-tune feel and control to suit your load and riding conditions. If your use-case is outside the norm, a suspension specialist can further tailor the setup through service work.

Before you install

Confirm fitment for your exact BMW R nineT variant before installation. After fitting, set sag using the preload adjuster and then use rebound adjustment to balance comfort with stability. If you are unsure on setup, note your current settings before changes so you can work methodically.

Serviceability/lifecycle

Like other Ohlins units, this shock is serviceable to maintain performance over time. Periodic servicing refreshes oil and wear parts and is also an opportunity to tailor valving or spring choice if your needs change. Regular servicing helps preserve consistency and ride quality.
