The 2015 Mtn. Dew ATV Motocross National Championship, sanctioned by AMA (ATVMX), begins with its inaugural visit to legendary Daytona International Speedway, for the first ever ATV Supercross on Tuesday, March 10. While this one-of-a-kind event signifies one of the most historic moments in ATVMX racing, it’s also the beginning of one of the most anticipated seasons in the championship’s 29-year history.
