2006 KDX 200, bought new in Oct. 2006, one of the last ones. I finally feel like I have the bike dialed in for the kind of riding I do (twisty desert trails with my kids). Not much in the way of mods:
I've got it dirty several times. Already smashed the stock pipe, bent the stock bars, and shredded the stock inner tubes. I do wash it after most every ride.
