Which is a more modern thumper a xr or a klx. I need one either a 250 or 300. They both seem like good trail bikes but I need something to keep up on a track with friends. If anybody owns one of these how do u like it? I think a xr 250 is aircooled but what about the klx? which has better power,suspension,steering,topend,lowend, etc..? and what about aftermarket parts?
