Ok whatever. Like I said This is not between the KX500 and CR500. But you sucked me into it. Yes the KX has more wins in the desert. The CR in the Motocross and hill climbs. The KX steel CHASSI and the KX's top end power made better suited to the desert. Every dyno chart I have show's the CR actually has more POWER than the KX stock. The Kx has a higher reving engine due to the pwer valve. Making the power freindlier and less explosive. I have every article of the two bikes in every mag from 1992- 2002. You should've bought that KX500af.
