Just got a 2011 yz450f at the begining of the week. Its looks awesome, and is fast as hell. But im already thinking im going to sell it. Been riding 2 strokes for the past year, and im not sure if the 4 stroke is that much better. I know im a little quicker, but I dont like having to worry about all the 4 stroke issues and worrying about my bike depreciating like crazy. Has anyone else recently went to a for stroke, to only go right back to a 2 stroke?
