Totally agree with pyndman. As much as a roadbike 'looks' like a racer, it's still a long way off.
Honda were stated as saying on their roadbikes (CBRs) that they base 60% of the bike for roaduse and 40% for track. They water them down, make them pass emissions and noise tests, make the engines go without a rebuild for.. well, pretty much life short of valve clearances, they allow oil changes to slip to 4000 miles, they have lights, wingmirrors, comfier seats, road based fairings, road friendly chassis... Essentially, their designed to put up with a large amount of variables - road conditions, rider ability, bad maintenance, poor weather - and still keep working.
When that base is turned into a race machine, certain parts of that engineering cannot be taken out by setup and switching parts allowed by the regulations.
GP bikes are a machine built with only the compromises deemed in the rules, and the compromise of making a bike as suitable as possible for all the tracks on the calendar. i.e. they need something that can be setup to work at a Laguna and they need something that'll work well at a Brno. The bikes only intention is going around a track with the best of the best riders, with excellent mechanics dedicated to setting up the bike to the best of it's potential.
