I think that a production based class would be good. It would keep the costs down for the teams, make the bikes slower than a one-off 600, and I think it would benefit the bigger sized riders. All thses tiny little guys that have come up from 125's and 250's (Rossi being the exception) have not fared too well in the MotoGP era. This year everone was saying Pedrosa wass too small to handle the big bike. Why would you want support classes that were designed for riders that wouldn't make good premire class riders???
I'm not asking for arguments here on specific riders I know there are a lot guys that have come up and been sucessful, Rossi, Melandri, Biaggi, and all this crop of new riders this year. But historically sucessful motoGP riders have come from the superbike series...
