I am in the market for another bike. Just sold an 05 yz450f. I probably can't afford any better then an 06 whatever. I have been so set on getting an 06 yz450f. Thru 2006 all I heard was the 06 is night and day better then the 05. I will admit I never felt turn comfortable on the bike and got tired quick but I am 39 but finishing top 3 in vet c. Now I here all the 06 complaining and now here the 08 is night and day better. Will the 2010 be night/day also better. I just wish I could ride one but don't have that option. Then I have a good deal on an 06 kx450 that maybe is better the the yamaha. All I want is good confident turning that will not tire me out so much. JUST DON"T KNOW WHAT TO DO!! Sorry just had to vent.
