The Tractive eX-CHANGE PRO Shock for the BMW R 1250 GS Adventure is a closed, pressurised damper designed around a sealed internal cartridge to keep damping consistent across changing temperatures and long rides. The gas and oil are separated to reduce aeration and help maintain a stable feel over rough surfaces. This unit includes an external reservoir and is supplied with a spring.

Design & features

  • Closed, pressurised architecture with separated gas and oil to help resist fade and maintain consistent damping.
  • External reservoir design to support thermal stability during sustained use.
  • Built as a complete shock replacement and supplied with a spring.

Tuning Controls

  • Electronic damping adjustment (plug-and-play style fitment).

Who is this for?

  • Riders who want electronically adjustable damping while retaining a self-contained, purpose-built shock assembly.
  • Owners using their R 1250 GS Adventure for mixed-surface touring where consistent damping feel matters.

Before You Install

  • Confirm compatibility with your exact BMW R 1250 GS Adventure variant and any existing electronic suspension equipment before installation.
  • Set spring preload and any available electronic settings after fitment to suit rider load and typical luggage/passenger use.

Serviceability/Lifecycle

  • As a sealed, pressurised unit with a separated gas chamber, correct servicing requires appropriate suspension tools and procedures.
  • Plan periodic inspection and servicing based on usage conditions (dust, water crossings, and high mileage will shorten service intervals).
