As much as I’d love to see “true” prototypes racing each other the sad reality is that it’s too expensive as the economic problems in Europe and Japan are hitting motorcycle racing in a big way.
If it wasn’t for the CRT teams this years MotoGP grid would have been embarrassingly small and contrary to some predictions the world hasn’t come to an end because some GP bikes are now “glorified superbikes” instead of full prototypes.
I think the main problem I’d have with the proposed changes would be the one bike per rider rule; the teams would still be taking several full bikes worth of spares to each race so why stop them having a spare bike that they can use if they crash in practice & quali and as a wet weather spare for the race ?
