Seriously? Dude check your research. He's one of the most winningest riders of all time. You've got to be joking, right?
what does "winningest" mean? Is it total number of wins? That would be Agostini. Is it highest winning percentage? I'm not sure, but I'd bet he's not number one in that, either. There's any number of ways to consider what "winningest" is. That said, everybody on the planet knows (or should know) he's the greatest of all time.
