The Ohlins BM309 STX 46 Adventure rear shock is a replacement suspension unit designed for the BMW K 1100 RS. Built around Ohlins’ STX architecture, it is intended to deliver controlled damping and consistent feel across changing road and load conditions. External adjusters allow you to tune the shock to suit your riding style and setup.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on predictable chassis behaviour and durable, serviceable construction. The STX 46 Adventure family is aimed at riders who want a composed ride and clear adjustability without complexity.

Who this shock is for

  • BMW K 1100 RS riders replacing a worn rear shock with a dedicated Ohlins unit
  • Riders who want external adjustment to suit different loads and riding conditions
  • Owners who value a shock that can be maintained and reconditioned over time

Shock design & features

This is a mono rear shock from the Ohlins STX 46 Adventure range with oil and gas separated design for stable damping. It is supplied as a complete unit with spring fitted, intended to suit the specified application.

Tuning controls

Adjustment is provided for rebound damping and compression damping, plus a hydraulic spring preload adjuster to accommodate changes in rider weight, luggage, or passenger use.

Before you install

  • Confirm fitment for BMW K 1100 RS and check clearance with any accessories or luggage hardware
  • Set rider sag and preload first, then refine rebound and compression to match your tyre choice and riding conditions
  • After installation, re-check fasteners and settings once the shock has bedded in

Serviceability/lifecycle

Like other Ohlins units, this shock is designed to be serviced to maintain performance over its working life. Regular inspection and periodic servicing helps keep damping consistent and protects internal components.
