Until 2002 was the hosting of the World Motocross Championship in three classes by engine capacity limits (up to 125 cc to 250 cc and 500 cc ) were distinguished. Because of these technical specifications only two-stroke engines were used. In 2003, the new class " Motocross GP" analogous to the MotoGP was introduced in road racing. Registered in this class were motorcycles with two-stroke engines and a maximum of 250 cc and four-stroke engines with 450 cc displacement. In the small class (125 ) additional four-stroke engines were admitted to 250 cc. In the large class (650), the displacement was limited to a maximum of 650 cc.
Since 2004, the World Championship in the MX1 (250 cc two-stroke and 450 cc four-stroke ), MX2 ( 125cc two-stroke and 250cc four-stroke ) and MX3 is (500 cc two-stroke and 650 cc four-stroke ) discharged.
