The Motocross line was launched in 2000 as a successor to the Honda XR series. The full sized motocross bikes are equipped with liquid-cooled, single-cylinder four-stroke engines that are available from 149 cc to 449 cc. They now have dual-sport motorcycles. The more trail friendly Motocross have simple air-cooled engines, and are available from 50 cc to 230 cc.
