I made a simple luggage rack that attaches to the Givi SR357 frame. I think a lot of hard top boxes overwhelm the appearance of the FJR. I just wanted to be able to attach a smaller semi-soft top box of some sort. I got a 4mm thick, 300mm x 400mm carbon fiber plate, trimmed it to shape for the Nelson-Rigg large Commuter bag, added 4 footman loops for strap attachments and voila - lightweight and strong all-purpose rack. Waddya think?
