The thrill of upgrading CCs

Nope a stock standard 07 R6 has 139 bhp at the rear wheel. 4-5 less with the non cold air intake versions. I know mine does dont no abt urs?.

Yeah. Course it is, dude. As you're so knowledgeable, perhaps you'd like to inform me how the UK's superbike magazine measured the '07 R6 on a dyno and got 104.01rwhp @ 14,381 rpm. If you're very lucky, with ram-air operating, you might just hit 139bhp at the crank but there's no bloody way on earth you're getting 139bhp at the rear wheel from an R6 unless you're a) running nitrous, b) running a turbo, or c) on crack.

Yes I know was a bit of a typo sayin the rear wheel and u shuda known that since ur sooo smart. everyone knows that an R6 has 140 at the crank. mate I can appretiate ur help and friendly advice but if u think that because u have a few more miles under ur tires than I do so u can just disrespect people u have another thing comming buddy. lets be a little sensible and end this here. Thanks.

also ill take option c.

That's a bit harsh, mate, 90% of the time the manufacturer's specs and what is quoted is what you get at the crank. I always quote my little CB as 26HP, but it's not making anywhere near that at the wheel. That horsepower figure is just what the manufacturer quotes.

Well, considering Yamaha actually claim 127hp at the crank, the claim of 139hp is a little optimistic. Ram-air makes a difference, but I very much doubt it's 10%. Especially when you consider Yamaha are probably taking that into account when they quote their figure. Honda, for example, claim 117hp for the CBR600RR, but real-world rear wheel dyno figures show the Honda as the most powerful of all the Jap 600s.

Im not so content on my little bike, I pulse with jealously when I see others on their faster bikes!!

Bet you're not jealous of me ... bigger bikes do have their downside y'know
