I'm looking at buying at YZ450F and have read that the changes made in 08 make a very noticeable difference in the handling characteristics. Can any of you that have owned both confirm this? There's a plethora of YZ450F's for sale here locally. If I can find a real good deal on an 06 or 07 over an 08 or 09 it will leave me more $$ to spend on making to woods worthy. Thanks!!
