Motocross, MotoX or MX, is an all-terrain motorcycle racing discipline practiced on off-road circuits. Using natural terrain features with jumps and berms, riders race each other around the track at the highest possible speeds without losing control to cross the finish line first. Freestyle motocross is a spectator sport focused at performing acrobatics while jumping high in the air, where riders are scored on style and difficulty.
