The Ohlins BM841 STX 46 Supersport rear shock is built for the BMW R 1100 S, focusing on controlled damping and consistent chassis behaviour. It uses a separated oil/gas design to help maintain damping stability through sustained, hard use. With independent damping adjustments, it supports a more precise setup for your load, tyres and riding style.

Ohlins | Made to race, perfected to ride

STX technology comes from Ohlins’ track development, adapted for performance road and supersport applications. The aim is repeatable damping behaviour and clear feedback, so the bike stays composed when you are braking, turning and driving out of corners.

Shock design & features

  • Monoshock rear unit to suit the BMW R 1100 S.
  • Oil and gas are separated to reduce aeration and maintain damping control under heat.
  • STX 46 Supersport architecture developed for accurate damping response and stability.

Tuning controls

  • Rebound damping adjustment to manage how quickly the shock returns after compression.
  • Compression damping adjustment to control support under braking, bumps and load transfer.
  • Spring preload adjustment to set sag for rider weight and luggage/passenger use.

Base setup (factory preset)

This shock is supplied with an Ohlins base setting intended as a reliable starting point. From there, make small changes one at a time to match road conditions and your preferred balance between support and comfort.

Before you install

  • Confirm fitment for BMW R 1100 S and check clearance through the full range of suspension travel.
  • Set rider sag and verify that preload and damping adjusters move freely before final assembly.
  • After installation, re-check fastener torque and inspect for any interference after a short shakedown ride.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced to keep damping consistent over time. Regular maintenance helps preserve oil condition, seal integrity and overall damping performance as hours and heat cycles accumulate.
