RULEBOOK (click here>) NMA RULES: Enduro, Off-Road, Trial Series & Arrowing Guidelines


*We will update this section as the season progresses, so please check back periodically.*

The NMA racing rules are designed to ensure that the racing is both fair and competitive, and as safe as possible for both racers and spectators. Please take a few minutes tofamiliarize yourself with the Rule Book before your first race.

First and foremost, the following are CHANGES for 2023:


*Two new Youth Classes – Age is based on youth age as of January 1st of the race year.

  •  Junior B – Age 12 and Under.  Maximum front wheel size of 19″
  • Junior C – Age 8 and Under.  Maximum 50cc (2 stroke) or 70cc (4 stroke).

*Season Points for Youth Classes

  • Will be scored the same as all other NMA Racing events.
  • Youth classes will be exempt from the 50% rule; completion of one lap and taking checkered flag results in a finish being awarded.
  • Minimum events to qualify for season awards will be based on current NMA Racing rules. Only the events with youth races will be counted towards the minimum.
  • Event throwaways will be treated same as all short course classes.

Quick Facts for each Series:


*There will be TWO throwaways for the season
     **EXCEPT the AA class which will have one throwaway

*ALL Competition License holders will display the class letter on their bike (See Table 1B)
     **In AA class, ALL participants (Comp Licenses holders and not) need to display class letter

*A WORKED EVENT will count towards events to qualify

Below are a few common mistakes racers make that can result in disqualification.

 Leaving the course to return to the pits. Once a rider willfully leaves the course they are automatically disqualified, even if they are pushing their bike and intend to return to the point that they left the course. Riders must follow the course to reach the pits.

 Pitting outside of the pits. Riders must enter the pits to fuel and even to receive new goggles, gloves, water, etc. Riders stopping to meet pit support on the live race course can create dangerous situations and may result in disqualification.

 Riding backwards on the course, even for a short distance. This is a definite No-No!

 Not finishing the race. A rider must cross the finish line under a checkered flag to be counted as a finisher. Riders do not receive credit for laps ridden and will be scored as a DNF if they do not finish under the checkered flag.

As always, if you have a question, please ask. We are here to help make this a great experience for all.

NMA competition events follow a common set of rules designed to promote safety, fairness, and competition.
