Not to dog the Kawi engineers, but I believe I read that there were other factors in the limitation of the 12R's top end.
Then, again- I don't want to 'question' Muzzy's results either.
I have heard that some last minute "changes" were made to appease the growing threat of restriction from certain European communities. (also note that the Hayabusa isn't as fast this year) I read somewhere of 12R's whose oil pans were seemingly filled up properly, yet were actually way overfilled, killing performance, and in some cases motors.
I also recall something about a remapped "black box" which inhibits fuel and timing slightly- enough to satisfy those who don't find bikes like the 12R quite PC enough. However, I do believe Muzzy and some other aftermarket companies have found ways around it already.
If you just yank the catalyst out of your bike's exhaust, aren't you then speeding the exit of the exhaust gas? Which is a good step towards more power in any motor, but what would you do to increase the fuel input to balance out that equation? (it's injected, right?)
Anyway, I agree that Kawasaki wouldn't just release a bike willingly that they knew wasn't going to be the new king of fast. I think it is/was a bunch of factors that figured in to taming the 12R. Just seems too simple that one could just remove their exhaust catalyst and blammo- all the missing top end is back.....
