Re: All 4 new 1000's on the dyno on same day.
I'm not surprised at all. Kawasaki was making decent power from their 899cc ZX-9s and they have always been able to make strong engines. What's interesting to note on that graph is that, despite being a year old, the Suzuki still has the most usable power. It's not up until about 9k that the ZX-10 starts pulling away. These were taken for one bike from each manufacturer, and it's possible that one was a "weaker" engine while another was stronger. It might be more accurate to see an average taken from, say, 20 bikes of each kind, and then overlay those averages.
I'm sure they're all going to be good bikes and anyone who wants one probably won't go wrong with choosing whichever bike they like best by looks. For me, it would probably be the Gixxer or the ZX-10. If I could agree with one thing that I've read from Max McAllister, it would be that most if not all bikes today aren't hamstringed by power. Their shortcomings, rather, are almost always related to their suspension and setup.
