I read it in an article in a MC mag, and it was per bike.
As far as the other stuff goes, yeah I'd say it's all in the development not the actual parts to build it. They may not sell GP bikes straight off the floor, but lucky for us there's the trickle down theory. I mean look at our TL's, 15 years ago what would it have cost to get magneium valve covers? Now you can purchase ceramic coating bearings and other things, that as computers and CAD keeps developing, our (humans) ability to use materials that were probably used to make rockets and satellites but all but impossible to get for the average public. Hell, Carbon Fiber alone, was one of those, WOW!, things that came out, now it's an everyday thing. From bikes to my gloves.
Are there any privateers in GP racing? Seems like there'd be no point since the bikes are used to test technology and parts that will eventually make it into production bikes. I thought the privateers were just in AMA.
Oh well.
