Builder Notes
This kit was built to solve real‑world challenges that builders face when integrating an M8 drivetrain into the FXR chassis. The included crossmembers, tie‑ins, motor mounts, and filler plates ensure correct alignment and repeatable geometry eliminating the trial‑and‑error that typically consumes hours of fabrication time. For the cleanest install, mockup your drivetrain first, then tack all components in place before final welding.
Disclaimer: This product requires permanent frame modification, including cutting and welding. Installation should only be performed by individuals with appropriate fabrication experience. Improper installation may result in unsafe conditions, property damage, or personal injury. By proceeding with installation, the installer assumes all responsibility and liability for the work performed and the resulting vehicle condition. If you are not experienced in motorcycle frame fabrication, professional installation is strongly recommended
