ges, Yes, I will put a trunk on it. I have a GIVI E529 mount for the pre-13 650s and Coocase trunk from another bike. I mounted the mount and trunk without the rear cover and the seat clearance was good. I assume there will be no problems using the standard GIVI E529 mount with the new cover. I guess the new trunk mount from GIVI with the new number includes some plastic piece to cover the open area when the passenger backrest is removed.
