With 49,000 miles of touring on my Busa, I think I have tried almost everything. Ventura does make a system for the Busa, as does zenrail. I just used the ventura sport rack and RKA saddlebags till this year. Then I got a complete Givi wingrack setup off a friends FJ1200. I made brackets by using my ventura sportrack mounts since givi does not make them. If you have an aluminum subframe, be careful. Mine just broke up in Laconia.
