Was thinking Honda are stretched thin. They must have the largest coverage of participation in major racing series... F1, Indy, MotoGP, SuperBike, BTCC. Surely they would be better dropping something and focusing their efforts!
I'm sure there will be someone now list every single category that a Ferrari or Mercedes participate in... but I don't believe it is the same as they are mostly race versions of the same product development (by and large)
If I were Mr Honda I would drop Indy and super bike.
