I am probly not the only person that saw this, though it was only up for a short time (probly cause the guy got 400 emails in 30 minutes). Some guy in Iowa was Suzuki RK67 like this:
for $200. Water cooled (boo), but 50cc 2 cylinder, 17.5k redline, 105mph and 14 gears. Impractical, uncomfortable, not street-legal...but holy crap I would drive the hell out of it.
