Thanks Bill, yes this was the previous incarnation of the bike. And it went like the clappers! I have another video of riding it that I will post below from the Missoula rally. Friends Ted and Geoff built this Ducent / Vincent / Ducati special from a rolling chassis that Ted had. They couldn't find a Vincent engine and so they carefully fitted a 900SS engine into it. They didn't change any of the frame but instead made special mounting attachments, so that the frame could accept a Vincent engine again in the future. Geoff subsequently got the bike from Ted and then purchased a Vincent project from John Ulver. He then transformed it into this beautiful red Rapide! It's a great story.
