AMA Motocross Rules & Regulations

The American Motorcyclist Association (AMA) is the world's largest sanctioning body for motorcycle competitions. Established in 1924, the AMA regulates competitions, classifies riders and sets equipment standards. The organization prohibits discrimination. Authorities review and make any necessary modifications each year. The AMA publishes the rules for motocross competitions and makes them available on the Association's website.

  1. General Rules

    • Each competitor must be a member of the national chapter of the AMA as well as the district organization if the local meet requires it.

      Amateur riders must be at least 12 years old, and off-road racers must be 14 or older to ride motorcycles 250cc or larger.

      Only Class A riders may compete for cash prizes at standard meets.

      All officials, race personnel, mechanics, riders and anyone associated with photographers or riders are prohibited from being under the influence of drugs or intoxicants. Consumption of alcohol is also prohibited.

      In addition, riders who direct foul and abusive language at officials or promoters will be disqualified for the entire meet. Riders are also accountable for the behavior of their pit crews and families.

      Riders are restricted to one machine in any class. However, riders in different age groups may share a motorcycle. Violations will result in disqualification.

    Classifications

    • AMA competitors are classified as "A," "B" or "C," with "A" being the highest class. A rider advances based on her Rider Performance Value (RPV). The choice to move up is made by the rider. It is prohibited to attempt to force a Class B rider between the ages of 12 and 15 years old into Class A competition, regardless of how many advancement points she has.

      If a rider wishes to return to a lower class, she may do so one time. However, the AMA must approve the reclassification. Officials must consider the rider non-competitive in the group she is leaving.

    Entry Rules

    • Promoters are authorized to refuse entry to a rider who has yet to make arrangements to pay medical bills related to injuries sustained at a previous meet.

      Youth entrants are restricted to three classes for the entire day if youth and amateur events are being run on the same day and location.

      An amateur or youth rider may use the same motorcycle in more than one class as long as the rider and his bike meet the class qualifications.

      A rider's age on January 1 sets his age class for the remainder of the year. He is unable to advance to a higher age group unless he was eligible before January.
