I would say the top 2 are the other way round to Chuck. Moto GP is the pinnacle of racing with Superbikes being next. Moto GP bikes are cutting edge whereas I believe Superbikes can be bought on the high street.
Riders are always looking to move up to Moto GP and the ones that aren't quite up to it go into Superbikes.
