Morgantown, W.Va. (December 19, 2011) – The ATVPG announces today the 2012 Supplemental Rules and Class Structure for America’s most prestigious and longest standing ATV racing series – the AMA ATV Motocross National Championship Series.

The class structure has undergone minor changes in both the youth and amateur categories. Highlights include splitting both the Girls (8-15) and the 90 Modified (8-15) classes into two separate age groups, accordingly.

“We recognize the continued growth in youth ATV racing,” said Sam Gammon, Director of ATVPG. “We feel that splitting the Girls and 90 Modified classes will give younger racers a safe platform to compete as they progress in both age and skill level.”

Another change comes in machine eligibility for the 90 Production (8-15) class. The Production class will be limited to shifter machines only.

“In order to reflect the evolving technology of machines, we will continue to develop our class structure in order to maintain a fair and balanced level of competition,” Gammon added.

The 2012 Supplemental Rules and Class Structure will be tentative and open to public comment through the end of the year. Questions regarding rules and classes should be directed to info@atvmotocross.com.
