I have a '07 YFZ 450 and love it to death, it's snappy as hell, great suspension, and fits me like a glove, I also have a '04 predator 500, and I'm not a huge fan, it's big and bulky, feels like your riding a utility quad with the looks of a sport quad, so I agree with these guys, it's what fits you best, test drive/sit before you buy for sure. My brother has a '08 Raptor 700 SE and that thing is a beast too, I love the EFI on it, just cause you can go from my house (sea level) to his neck of the woods (5000 feet) and ride the same, my YFZ is carbed and you definately can't set it and forget it lol.
