I think everyone knows that I am a 250R fan, but I just think the two stroke is more fun to ride. In a Mx situation, I feel that a 330cc R is no different in track speed than the 4 strokes. They both have pros and cons, its all in what you prefer.
The chassis is where the difference comes in. If you want the best ride possible, my opinion would be an aftermarket 250r chassis cr500 or crf450 link, with a CRF450R engine.
The production bikes today do not handle as well as the aftermarket R bikes did. They are getting closer, but not there yet.

Oh boy, you just stirred the pot with that last comment.
But I agree 2 strokes are much more fun to ride. -Mark
