Supercross riders from the 2006 series in AnaheimSupercross is a cycle racing sport involving racing specialized high performance off-road motorcycles on artificially-made dirt tracks consisting of steep jumps and obstacles. Professional Supercross contest races are held almost exclusively within professional baseball and football stadiums. Many notable differences exist from regular motocross. Supercross tracks generally have much tighter turns and are more technical than motocross tracks due to the limited space of an indoor arena. The supercross season takes place during the winter and spring months, partially due to more controllable indoor climates involved.
