The Ohlins STX 46 Street rear shock for BMW R 1150 R and R 850 R is built to deliver controlled, predictable damping for real-world road riding. It’s designed to improve chassis stability and tyre contact through corners and under braking, with a consistent feel as conditions change. This unit suits riders who want a serviceable, tuneable suspension upgrade without compromising everyday usability.

Ohlins | Made to race, perfected to ride

Ohlins road shocks draw on the same damping principles used across the brand’s competition programs, then refined for street comfort and control. The focus is on maintaining grip and balance, so the bike responds cleanly to inputs and stays composed over imperfect surfaces.

Shock design & features

This is an oil/gas separated monotube rear shock design, intended to maintain damping consistency during extended road use. The layout supports stable damping behaviour and a controlled ride feel across a wide range of speeds and road textures.

Tuning controls

This shock provides rebound damping adjustment to tailor how quickly the rear suspension extends after compression. It also includes a threaded spring preload adjuster to set ride height and sag for rider weight, passenger use, and luggage.

Base setup (factory preset)

Ohlins supply these shocks with a baseline setting intended to suit typical street use on the listed BMW models. From that starting point, small changes to preload and rebound can be used to correct common issues such as wallowing, harshness over sharp edges, or a rear end that feels slow to recover between bumps.

Before you install

• Confirm fitment for BMW R 1150 R and R 850 R with the correct mounting style and any model/year differences.
• Set sag after installation by adjusting spring preload, then fine-tune rebound to match tyre choice and riding conditions.
• Inspect linkage/bushings (where applicable) and mounting hardware condition during installation.

Serviceability/lifecycle

As with other Ohlins units, this rear shock is designed to be serviced and revalved as required over its working life. Periodic servicing helps maintain damping performance, especially if the bike sees frequent commuting, spirited road riding, or varying loads.
