The Ohlins BM450 STX 46 Street rear shock is built for the BMW R nineT, focusing on controlled damping and clear feedback for real-world road riding. It uses a gas-pressurised design to help maintain consistent performance as conditions and pace change. The result is a more settled chassis and improved confidence through corners and under braking.

Ohlins | Made to race, perfected to ride

Developed from Ohlins race program experience, the STX 46 Street platform is aimed at riders who want higher quality damping control without losing everyday usability. It is intended as a direct-fit rear mono shock replacement for the R nineT.

Shock design & features

  • STX 46 Street rear mono shock for BMW R nineT
  • Gas-pressurised damping architecture for consistent response
  • Valving developed to improve traction and chassis stability

Tuning controls

This rear shock provides external damping adjustments for both compression and rebound, allowing you to fine-tune support under braking and acceleration as well as ride comfort over rough surfaces.

Is it right for you?

It suits riders who want clearer front-to-rear balance, more composed handling, and the ability to tailor damping to load and riding style. If you regularly change between solo riding and carrying luggage, or you’re chasing more consistency in faster road riding, the added adjustability is particularly useful.

Before you install

Confirm fitment for your exact BMW R nineT model and year, and note this unit replaces BM 440. After installation, set sag and check clearances through full suspension travel before road testing.
