New Classes and New Rules Announced For The 2007 AMA ITP/Moose ATV National Motocross Championships


Presented by Parts Unlimited

Morgantown, WV – The ATV Promoters Group (ATVPG), in cooperation with AMA Racing and the ATVA, announces new classes and new rules for the 2007 AMA ITP/Moose ATV National Motocross Championships Presented by Parts Unlimited.

The most exciting news is the evolution of the AMA Pro ATV Championship. Since its inception, the ATVA nationals have showcased its fastest and best riders in the “Pro Class”. Now, these riders will be recognized as professional racers by AMA Pro Racing, and will carry the newly-created AMA Pro ATV license.

To supplement the Pro riders, this year’s series includes 31 amateur classes. Last year’s Pro Am Unlimited and Pro Am Production classes have been combined into one Pro Am class. A new Pro Am Women’s class will showcase our premier women racers. Pro Am Women riders may be classified as “A” riders at non-national events. Amateur women racers can compete in the Women’s class for amateurs. The restructuring of the Women’s class will better address the varying levels of competition in those ranks, and enable newer racers to compete with riders of their skill level.

A new Vet 30 Plus B/C class will accommodate the growing number of veteran racers. In the mini-quad ranks, changes have been made to keep the classes consistent with the changing machines available to the youngest ATV racers. In the Youth classes, engine displacement reductions will not be permitted to meet class limits.

The new rules also clarify the definition of ‘Limited’ in the Production Limited and 50cc Stock Limited classes, as well as specifying approved machines and modifications in the youth classes.

Finally, a sound level limit of 99db will be enforced in 2007 for all classes, in order to bring the series in line with the rest of AMA Racing.

These changes are set forth in the ATVA Supplemental Rules, which supplement the AMA Sports Amateur Competition Rulebook. Visit for the complete, updated supplemental rules.
