The Ohlins BM349 STX 46 Street rear shock is built for riders who want more control and consistency from the BMW R 1150 R Rockster’s rear suspension. It uses a monotube architecture with a separated gas and oil arrangement to help maintain stable damping under sustained use. Designed for road riding, it focuses on traction, chassis support and predictable feel.

Ohlins | Made to race, perfected to ride

Ohlins street shocks draw on the same damping principles used across the brand’s motorsport programs, adapted for everyday road conditions. The result is a controlled, confidence-building rear end that stays composed across changing surfaces and loads.

Shock design & features

  • STX 46 Street monotube rear shock format
  • Oil and gas are separated for consistent damping behaviour
  • Purpose-built fitment for BMW R 1150 R Rockster

Tuning controls

This shock includes external rebound damping adjustment to tailor how quickly the rear returns after bumps, braking and acceleration events. It also features adjustable spring preload to set ride height and support for rider weight, passenger and luggage.

Base setup (factory preset)

Ohlins supplies this unit with a baseline setting intended to work as a starting point for road use. From there, rebound and preload can be refined to suit tyre choice, riding style and typical loading.

Before you install

  • Set sag using spring preload before fine-tuning rebound
  • Confirm all mounting hardware is in good condition and torqued correctly during installation
  • After installation, re-check settings once the bike has been ridden and settled

Serviceability/lifecycle

As a rebuildable Ohlins unit, the BM349 can be serviced to restore damping performance over time. Regular servicing helps maintain oil condition, seal integrity and consistent feel as kilometres accumulate.
