The Ohlins BM654 STX 46 Street rear shock is built for the BMW R nineT and R nineT Pure, focusing on controlled damping and consistent feel on the road. It uses a gas-pressurised, oil/gas separated design to help maintain stable performance as conditions change. Designed as a rear mono shock, it’s intended to improve chassis support and traction through better-managed suspension movement.

Ohlins | Made to race, perfected to ride

Ohlins street suspension draws on proven damping architecture with practical adjustability for real-world riding. The aim is predictable feedback and stability without compromising everyday usability.

Shock design & features

  • STX 46 Street rear mono shock configuration for BMW R nineT and R nineT Pure
  • Gas-pressurised, oil/gas separated construction for consistent damping behaviour
  • Valving developed to support traction and chassis control during acceleration and braking

Tuning controls

  • Rebound damping adjustment to manage how quickly the shock extends after compression
  • Length adjustment to alter ride height within the shock’s adjustment range

Base setup (factory preset)

This shock is supplied with an Ohlins-fitted spring and baseline settings intended as a starting point. Set sag and confirm ride height before making damping changes, then adjust rebound in small steps based on grip, comfort and stability.

Before you install

  • Confirm model fitment: BMW R nineT and R nineT Pure
  • Check clearances and torque settings during installation, and re-check fasteners after initial rides
  • If you change ride height via the length adjuster, verify handling balance and stand clearance

Serviceability/lifecycle

Like any performance damper, periodic servicing helps keep damping consistent and internal wear under control. Service intervals depend on use and conditions; regular inspection for leaks and bushing wear is recommended.
