Thinking of adding a KDX to the garage this winter and was looking for some opinions. There is a 300-400 dollar difference in the two bikes new and I was wondering if the 200 would be a better bike than the 220 if you were take that money and put it into a pipe, better tires and other little things like that. Should I do a 200 and lightly modify it or the do the 220 and ride it stock?
