Aye,159 at the wheel out of a standard bike does fook all for me 




As for looking like streethawk...........Mr R1 - you have an excellent point 

[Jon177]

The side looks like the first fuel injected R1, why have a copy when you can have the real thing?  What ever happened to aerodynamics?  Someone on a US forum dynoed a new one, a hugely unimpressive 158.7bhp, followed by ten pages of excuses from people who believe advertisements.

MCN dyno'd it at 171 and fast bikes Dyno'd it at 165.

[doug_zx10r]

So we have 159, from a private owner who'd be expected to brag about big numbers, and 165 and 171 from corporate sponsored (through advertising and test bike supply) mags.  If they are all right then I'd say quality control was going to be a huge issue with this bike, or there's some seriously dodgy dynos around.

But that is a US version producing 158.7

You're talking as if 159 is NOT a big number.

I dunno,maybe you need more?

Jumping from 159 to 171 at the wheel is no big shakes mate - altitude,humidity,smoothing factors in software,vagrancies in tolerances of engines etc etc can all add up to differences greater than the 12bhp you've mentioned.

Good luck with the conspiracy theories though 

[doug_zx10r]

The guy with the 159 has bought it to race, so maybe it does matter to him.   

There's no conspiracy theory, a cheap shot that's often used by people with no reasoned argument to put forward.  I've bought enough disappointing bikes over the years based on 'rave' revues to know that the manufacturers and press are often economical with the truth.

ohh an 8% difference... how could that possibly happen between a bike made for a different market ( with massively different emission regs) on one dyno ( of unknown make or last calibration) and another on a different dyno( still probably uncalibrated).
As has been said loads of times before, only a direct comparison of all bikes in that class on the same dyno with at least 2 bikes of each model tested is worth looking at. Oh and if you can tell the difference between 159 bhp and 171 you are wasted in your current job!
PS
I saw the 08 model on the road on saturday (guy said his was the first registered) and it looked awesome even with the indicators. The 08 R1 may be the prettiest bike, but the ZX looks proper mean and more like a race bike. Side by side it is also smaller than my 04 to look at.

Right chaps,

No more bickering about the differences in BHP for this thread please otherwise I'll start to delete all the references.

It's not what this site is about, healthy debate is aceptable & most welcome, but cheap jibes at one another we don't want.

I think you're mixing up normal US emission regs with the California extra stringent ones.  My comment was based on the advertisements, 190 to 200 bhp with ram air effect, this bike is making the same as last years bike.  Bikes nowadays don't need much running in, and a bike that Kawasaki claim to be track-biased should need less than most.  I don't think anyone can teach the Japanese about metallurgy, or quality systems come to that, so I'd be surprised at an 8% difference between bikes, production bikes that is, as opposed to factory produced bikes supplied to the magazines.  The bike was advertised with the quietly forgotten pressure cast five spoke wheels, and seems to be supplied with last years six spokers, so I'm left wondering what part of the claims for the 2008 model are we to believe.  Does the quoted all-up weight include the lighter wheels? 

I'm happy to be given an explanation or a good argument, but all I seem to read are excuses.  It's a US bike, so what, it will be raced in the US and their adverts claim the same output.  The other bike got a jump start on the video, that's life, how many times does the guy on pole bog down on the start?

I was reading an article from a magazine on the launch of the gen 2, raving about the 'powerful' brakes, which just about sums up how little you should trust a magazine review.

once you have 125 bhp at the rear the rest is more than any of us need in my opinion so the figure bashing does nothing for me at all, at the end of the day when I ask myself does it matter each time the answer is no. different dyno's and different operators can make a figure different for the same bike so again what does it matter.

Most of us buy a bike because we like the look more than anything and if I had the money I'm not sure but would probably have one, afterall I'm keen on replacing my rear with an 08 

The bike looks nice in my opinion as do many bikes today
