I have seen 750's in 600 Frames, and I have heard about 1000cc in a 600 Frame. But the Busa Motor is not especially compact, I am just guessin gI am not a fabricator but I would say NO it's not possible. However, just about anything can be done if you have enough skill and enough money. But as for just slipping the Busa motor in there with minor hassles...I would say no way... FWIW
