Now this is what I call a motor swap! I saw this crazy picture and had to share it with all of you (http://www.strangedangers.com/content/item/110681.html). This is a one off custom bike built around a Ferrari 308 motor. In pure Ferrari fashion, I bet this thing would drain the gas tank with one crack of the throttle. Perhaps this is what gave Triumph their motivation behind building the Rocket III (http://www.triumph.co.uk/usa/3435.aspx)?
Cheers,
