2011 KAWASAKI KX250F , More AMA Lites championships than any motorcycle in history!Its an old refrain: The factory guys get all the good stuff. Their bikes are faster, lighter and just plain tricker than the motocrossers you can buy off the showroom floor. Theres some truth there. But thats changing. The gap between production and factory-prepped motocrossers has never been narrower. And with the introduction of Kawasakis massively reworked 2011 KX 250F, that gap just shrank a little more.
