Always a fun debate.
I like 2 strokes much better for a number of reasons, but I don't bash on the 4's like some 2 stroke fans do. I think 2 strokes still have a future, especially since KTM is supposed to be releasing a direct injection 2 stroke.
What do you guys think? I wonder what would happen if you put one of the SX riders in a main with a 2t? That would be interesting to watch.
