'08 was better, but a mellow engine;
'09 the one to get before Yamaha destroyed the line with the '10-'11 design
I have an '06 YZ450F and love it, the beasty motor
I think when it comes to buying a good used bike, I have had the best luck buying bone stock, Vet ridden bikes (on trails only) where the bike was obviously too much for them to handle thus they are selling it. The likelihood that he bike is all clapped out, is pretty low. I look at the cases for wear, sprockets (to see if they are stock and how much wear they have), tires (are they the original stock tires?), and always pull the seat and look at the air filter. I avoid dune bikes at all costs. Clear give away on a dunes bike is the little black flapper by the carb hose discharge on the rear suspension being chewed up by the paddle.
I've had good luck with one former 4 stroke race bike and 2 bad experiences with 2 other 4 stroke former race bikes. I've only bought one bike I knew had been to the dunes - got a good deal and figured it was worth the risk (and it wasn't - lesson learned). The bikes I bought that were vet ridden on trails, no signs of dunes or racing were great. Just been my experience.
But at the end of the day, if you get a good enough deal on a bike then just buy it. Get it home or to your trusted mechanic and have a look internally. Doing a new top end and cam chain right off the bat is a good call regardless of the time on the bike. Perfect time to inspect the bottom end and head/valves. At that point, you know exactly what you got (or don't got).

BTW, I have had five 450Fs and they have all been used. Some were raced, some not. Just look for one that hasn't been abused, whether it was raced or not isn't really the issue.
I'd buy a fellow vet's garage queen that was raced twice a year over a bone stock "never been raced" trail bike any day.

I assure you you'll be much happier. There's a reason you see so many off road these days. Get a ride on one if you don't believe.
