In FIM Motocross there is MX1, MX2, and MX3. What is the difference between MX1 and MX3
the upper limit for MX3 for a four stroke is 650ccsnb73 said:. . . Since no one "really" makes a 500cc 2-stroke, the 450 4-stroke is also the open class bike.
Now wouldn't it be cool to see a Pro rider show up with a CR or KX AF
