As for getting a 400 to 100bhp so far they are at around 80 for a cheating bored out fast race bike.
Yes an RR is faster with the right rider, I have passed the odd one on trackdays. Not to mention a couple of 1000's. I am not kidding myself thought these guys were just on the wrong bike for them.
If I got a 600RR I doubt I'd be much fatser anywhere except a straight line, I know my limits (low)
Lets not forget a 250 stroker got 2nd in the Riderpower Survey
RR 7th Clarkie
