speaking of the zzr600... I don't know how firm you are on $3000, but you might be able to find a 2005 ZZR6 for a little more. The 2005-2008 ZZR6's put out 111hp, and I've never felt the need for more on my bike. I'm sure I could get plenty of people on the site to testify that the zizzer has no trouble at all keeping up with the other 600s
