I have around 60 hours on my 10 yz450. I have put it down hard on both sides and both rad's are a little squished. I have been reading posts about the gears, and I have been no clutch shifting the crap out of this thing. I would like a white one and mine is blue. I belive trade-in on mine would net me about 4,500 and a new white one is 7,200 from a local shop. I know there are not many changes (color/clutch arm) for 11, but I also dont want to put a bunch of money in mine and it not be worth any more than what it already is.
