The thing is - the R6 has ram air. Unless those numbers were run on the same dyno as the '05 - and one that creates a windblast equivalent to the bikes 'speed' - then this tells you very little. Yamaha themselves have said that they're claimed 133bhp is WITH ram air assist. Different dynos give different results.
Let's face it - the 2006 R6 is a b!thin' bike. A tiny little rocket of a bike (I've never felt more 'over' the steering head than when I sat on one). One that may redefine what 'high-tech' means in motorcycling.
That dyno info is excellent, even only as a reference.
One of the bike magazines called the R6 "the most focussed bike" in the Yamaha lineup. It was made for the track, and it won't do much else very well. I wish I could afford it... and afford to take it to the track as often as possible... oh, that'd be great!!
I've been saying it for days Seriously, i reckon Yamaha took a look around, thought "well, we can't compete on drivability and real world usability with the 636 or the 675, so let's not make even a token attempt..." If that's what you want from a bike, then fair enough.
I've ridden one, and the seating position isnt as bad as people seem. My only problem was that the angle of the bike makes you "nut hug" . The exhaust note is the sexiest I've heard from a stock bike EVER. I have pics if you guys want to see... O yeah, and as i'm sure everyone knows now the 17.5 RPM is non existent, all dynos show the bike peaking @ 14.8 and cutting @ 16k... it is still a damn sexy bike though... ;D
