Well, I sold my '05 CRF 450R on Saturday and bought a next to new '09 YZ 450F. I'm pumped ! I've had 7 MX bikes and all of them have been Honda's, but I decided it's time to switch things up a little. So now I'm going to be asking you guys which parts are interchangeable between years, 'cause I've got no idea with the Yamaha's. I was in the market for a brand new 450F and had found them around for around $5000 out the door, if anyone's looking in MN Heinin's Motorsports has 6 of the red/white ones left for $5050 out the door. I would have bought from them if I hadn't found this one. The story with this one is that the guy who owns the dealership took two 450f's and went South for a vacation. I guess they found something else to do instead of riding the bikes because this thing has next to no time on it. The salesman said less than an hour on each of them, it's never been on it's side - period, the nipples are still on the front and visible on the rear, and the clutch/stator cover are hardly scratched. I got it for $4499 out the door !!
