This week on The Racer X Show with Greg White presented by Chaparral Motorsports, we bring you racing highlights from around the United States.

The historic Loretta Lynn Ranch hosted its 33rd Annual Rocky Mountain ATV/MC AMA Amateur National Motocross Championship, where 36 National Champions were crowned following a week of intense competition amongst the best amateur motocross racers in the world. Greg White catches up with the man of the hour, 2014 AMA Horizon Award winner and dual Loretta Lynn’s champ RJ Hampshire, as he prepares to debut in the Lucas Oil Pro Motocross Championship this Saturday at the Red Bull Unadilla National.

The AMA Pro Flat Track Series made a stop in the Pacific Northwest on Saturday for the Castle Rock TT at Washington’s Castle Rock Race Park.
