I am having a hard time deciding on which bikes(brand) to get for me and my son, for a little casual trail riding.....crf150/crf230, ttr125/ttr230 or klx125/kdx200......I have read that the kdx is the best trail bike around, but the fact that it is a two-stroke has me a little turned off.....I have no mechanical skills, and have heard that the two stroke bikes need a little more attention between rides.........SLAYER :aj:
