For trail riders, there are very limited 2 stroke options. I know people buy 250 MX bikes, install woods pipes, and gear them down, but that doesnt create an ideal woods bike...ie, small tank, not ideal low end power, its geared so low there is no top end speed, etc. Once you outgrow the KDX 220, your options are the KTM 300 and thats about it. Trail riders have more or less been forced into the cost of maintenance. We can thank the big 4 for that...I havent talked myself into anything.
