Just wait till you read my 636cc ZX-6R review..... hehehehehehehehehe. Here's a hint: The Honda handles slightly better and the ZX-6R is way faster (Kawasaki claims a +9Hp increase for 2005, if the claim is accurate, it'd make a total of 117 AT THE TIRE) All-in-all they are both superb choices, if you ride a lot of twisties or participate in trackdays. -Sean
