ATVMX-Logo-3-21-13Morgantown, W.Va. – Defending ATVMX champion Chad Wienen will wear the coveted number one plate for the first time ever heading into the 2013 Mtn. Dew ATV Motocross National Championship, sanctioned by AMA, season opener this weekend. Wienen Motorsports/SSi/Walsh/Yamaha presented by Maxxis Tires and Team Vollmer’s Wienen will be up against the fastest four-wheeled ATV Motocross racers in the world this Saturday, March 23, at Aonia Pass MX Park in Washington, Ga.

The 2013 ATVMX Pro lineup boasts one of the most stacked fields in recent history with 24 riders expected to line up at the opening round of racing. With several veteran riders, past champions and new riders making their debut into the pro class, the chase for the 2013 championship title will be one to follow. Two-time champ and ATVMX veteran John Natalie contested Wienen for the championship in 2012 but was left short and finished second overall in the points chase. This season Natalie will be riding a MotoSport.com/Motoworks/DWT machine and looking to reclaim that number one plate.
