Yes that's true but with the ECU Jumper mod, the ZX6R jumped in front just behind the R6 in top speed and I'm sure the track laptimes would have much quicker had they tested the bike with it in place. I don'y understand why Kawasaki neutered the bike in the first place. None of the other manufactures had to do that to their 600's. And the whole undertail exhaust thing is what adds the extra weight. All that unnecessary piping and heavy *** muffler way up there. Raises the center of gravity way up.
