AMA Super Motocross Regulations

"Super-motocross" racing is characterized as the most extreme form of motorcycle racing. The American Motorcycling Association (AMA) uses regulations for two main purposes. Rules are intended to level the track for fair competition and safety, while allowing teams to fairly earn a competitive edge from innovation. "Super motocross" is the sport's most extreme convergence of road and dirt racing. Its rules seek to ensure that everybody is even on the starting line.

  1. General Equipment Standards

    • Every part on the bike is part of the rules governing super-motocross racing in the U.S.

      Super-motocross racing rules cover 26 separate categories, ranging from motorcycle equipment to rider-safe apparel worn by racers. The first most important condition is Section 1.2 (a): "Only motorcycles on the Supermoto approved equipment list may be used in competition." It may sound obvious, but such logic is extended into racing's constituent parts: engines, chassis, and materials. Even the colors on the number plates identify which type of race is being run (super-motocross plates are white with black numerals). The general rules of super motocross are so specific because the American Motorcycling Association sanctions races all over the United States.

    Technical Standards

    • Engine power is a key criteria for all categories of motorcycle racing.

      In addition to general regulations, super-motocross racers must adhere to specific protocol on weight, engine power and engine parts. Competitors in super-motocross race with 4-stroke engines. Racers must use originally-approved bikes, although they can modify cylinder materials and castings, cylinder heads and crankcases. In addition, super-motocross bikes must weigh at least 234 pounds.

    Super Motocross Lites Technical Standards

    • The "lite" category promotes fierce competition within size limits in multiple areas.

      Super-motocross "lite" racers compete on smaller bikes with smaller engines. Regulations related to forks and shocks are the most specific rules in the "lite" racing category. Inner and outer fork tubes, axle lugs, cartridge, and piston rods must be the originals, but racers can replace the other fork parts to gain a competitive edge. The shock body, shaft and reservoir may be modified from their original form. Engine displacement in "lites" must range between 200 to 250 cc.

    Super Motocross Unlimited Technical Standards

    • "Unlimited" means maximum engine power in the regulated motorcycle racing world.

      "Unlimited" super motocross is a broader regulatory category. Engine displacement is unlimited to a ceiling of 575 cc. However, racers and their teams must submit a list (for review and approval) of parts which have been replaced before the green flag drops. Bikes in the "unlimited" category must weight at least 250 pounds (excluding fuel).
