I think the 500 will be an advantage for sure. In a current frame he still shaves major pounds off over a 450 thumper. He'll whip the radiator shrouds off that thing. Why not put a Suzuki 500 in there? I mean damn, if you're going to spend that much money on one, have the engine blueprinted, ported, polished with custom pipe and heck, maybe even throw FI on that B...thing.
Anyway, this will not be the future, just something else NBC Sports will call an "EXTREME SPORT"....should be fun to watch...watch I said.
