Once again, don't stress on the weight. I own an 09 kx450 and the thing turns in quicker and can be snapped around in a corner just as fast or quicker than anything I've ridden in recent years, yet people somehow say the kxf is the heavy one, well those number are deceiving. And I'm sure yamaha didn't go through all this effort just to produce a pig! BTW did the person that released those pics from yamaha so early manage to keep their job? Now we know their source was spot on.
