Autobots! Roll Out!
Both motorcycle racing, but both very different. I try to watch both as much as I can, but which do you prefer? I like Superbike racing, as they use bikes that if I had the cash, could go to the dealership and ride home a tamed version of what they race. Don't get me wrong, MotoGP is awesome, but I'll never own a RC211V, and that sorta takes something away for me compared to Superbike racing.
