This could possibly hurt sales of the new CBR600RR simply because the competition is already available. I have no doubt that the new CBR is a great bike, but I've already seen the new ZX-6R, and it's quite lovely in the metal. Admittedly I wasn't prepared for how small it is, but at least I could go to the local Kaw dealer and buy one today if I had room in my wallet for an extra motorcycle...
Remeber, it's always easier to do things the hard way. Chango
