I'm posting that you don't know what you're talking about b/c you simply don't. The YFZ is much lighter than a 450R and on tap w/the Suz/Kaw. I've seen the weigh-in's in person, plus I've seen the same results from other weigh-ins.
Punks like you are what make the forums garbage. If somebody says you're wrong who is right you start a rant about the person being 15 or something. Grow up or leave the forums so they can actually be put to good use. I speak highly of the Cannondales b/c after 5yrs of no production, I still haven't seen a quad that is better. Some have better geometry, some have better control, lighter, etc. But the power curve/tunability, overall handling, torque, etc is what makes it number one in my list. My C'Dale race quad lasted me 2 full seasons and roughly 330hrs w/out even adjusting the valves. Ran person until tore down and it still lives today. If you wanna get into a bitching war then leave the site. I know that I've had a Honda 450R, a KFX now, and have ridden/raced other 450's and the most reliable I've ever seen has been my C'Dale. The 450R was more/less a joke to me but it has improved into a nice quad now.
And I make myself sound like I'm 15 yet I'm the one mentioning facts and not starting this kind of crap? I've most likely torn into more quad/engines than yourself, and have raced for quite a few years. When you can stand up and talk w/the real riders and stop doing the EXRiders preteen "you're 15yrs old" thing, come back. Until then; grow up. Posting a response to this shows your insolence.
