What the (*&& indeed. Like Scotty said, RV is good, because hes good. End of story. As far as two strokes hampering your ability to a ride a four stroke, thats just a flat lie. First off, RV has been caught practising on a KX125 and 85. Why would he be doing that if it hampered his ability to ride his competition bikes? Secondly, the vast majority of riding skills carry over from a 125 to a 250F, and likewise from a 250, to a 450F. Its just that the four strokes are nothing like as easy to make mistakes on, are more forgiving of the ones you do and make the track an easier place to live with. Thats it. The only reason this waste of oxygen is against two strokes, is because he wasn't getting as many kick backs when they ruled the roost.
