YOKOHAMA CUSTOM ROD SHOW

I was browsing some pics of the Yokohama show when I came across this beauty. I'm not even sure what it is. At first I thought it was an old Harley frame with a bolt-on hard tail, but the neck and motor look like they're from a Yamaha SR. The rear section though looks American. Whatever it is, it's definately one of the coolest bikes I've seen in a while.
