There's a series down in the states, just like this.
It's backed by the likes of Kevin Schwantz, Roland Sands and the guy who organized Superbikers back in the 70's.
You can buy a ready to race bike, or even a DIY kit from Roland Sands' company.
That would be street legal. I just got back from the CCS races at road america and seen a couple 450 super single road racers (motox's converted). Being a road racer myself, I'm seriously, seriously, thinking about giving my 450 this treatment. Its actually surprisingly easy.
