Below you will find links to the 2013 TENTATIVE ATVMX National Classes and Supplemental Rules, which supplement the already-standing AMA Amateur Rules. Please note: the AMA Pro division will have its own rules and they will be posted shortly.

Since these rules and classes are tentative, we will allow two weeks for public comment before they will be posted as final. Please contact [email protected] with comments regarding the 2013 Supplemental Rules and National Classes.

All new for 2013, we have put together a Class Detail Chart of eligible brands and models for the various classes in order to clarify which class each model is eligible for next season. This chart will be posted by the end of this week.
