Ok guys dont beat me up, lol. I own a busa, love it, running 9.3. also own zx10, 2006 have ran best 9.90 so far, stock. Just bought zx1400, new, havnt ran it over 6000 rpm yet, but can tell you it feels like a terd compared to the other two. But i did buy this one just to Ride in somewhat confort. Oh, yea I work for a Kawasaki dealer, or i would own three Busa's. You can not beat it in any area.
