Last month I sold my ZX6R and picked up an '04 CBR 1000RR. This bike is sick! The power is simply incredible, like a non-stop rush. The only thing holding you back is the size of your nuts and the amount of road in front of you! You run out of pavement real fast - luckily the brakes are incredible. The front brakes on this bike are so crazy, before I sold the 6R I rode it to work one day after riding the CBR the day before. It felt like my 600 had no brakes. I almost rear ended someone b/c I was already used to the 1000 - and the thing handles like it's on rails, the limits of this bike are just so insanely high. These current liter bikes are crazy - and I love it!
