The Tractive eX-TREME Fork Cartridge kit for the BMW S 1000 XR replaces the fork’s internal damping components with a closed, pressurised cartridge system. This sealed-cartridge architecture keeps damping performance consistent over long rides by separating the working oil from aeration and external contamination. The kit is aimed at riders who want clearer front-end feedback and more controlled support across changing road conditions.

Design & features

This is a fork cartridge conversion designed around Tractive’s closed-cartridge, pressurised layout. By using a sealed system, it helps maintain stable damping behaviour during extended use and repeated high-load events such as braking and rough-surface riding.

  • Closed, pressurised sealed-cartridge design
  • Replacement fork internals supplied as a cartridge kit

Tuning Controls

This kit provides external spring preload adjustment, allowing you to tune initial support and sag to suit rider load and preferred feel.

  • Spring preload adjustment

Who is this for?

Suited to BMW S 1000 XR riders focused on improved control and feedback for demanding road use and touring. It is also relevant if your riding regularly includes variable surfaces or changing loads (such as luggage or a passenger) and you want a front end that stays predictable.

Before You Install

Correct installation and setup matter for any cartridge kit. Plan to set sag via the preload adjusters and make changes incrementally to balance comfort, steering response and braking support. Professional fitment and setup is recommended.

Serviceability/Lifecycle

The cartridge kit is fully serviceable to support regular maintenance and rebuilds over its working life. Ongoing servicing helps preserve damping consistency and long-term reliability.
