We head to round No. 9 of the AMA National Grand Prix Championship Series as we take look at how dirt. Ike racers are taking advantage of free factory support direct from Yamaha. We meet Gary from Simi Valley Yamaha and ask him how such amazing factory support is made possible, meet some of the great factory motocross mechanics, find out what they spend most of their time servicing and we take a look at the extensive selection of spare parts available. Enjoy this look at free Yamaha factory support. #motorcycles #motocross #dirtbike
