What would you buy? I am looking at 600's and I don't know if I should buy an 06 or spend the extra money and order an 07. Help Me Please!

Depends on what you want. If I decide to go with the CF I wouldn't spend the extra $ for reverse and the new motor. I am in the same boat. I have a real nice 04 ZR900, but I want something a little more rider forward. I can get a real good deal trading it towards a 06 Crossfire 700. My other option would be dropping down the big $$$$$ for a 07 F8SP. I can get the CF for around 7000 and the F8 for around 9500. I think I might try the CF and give the 07’s a chance to prove themselves.
