Updated: 4.09.14


1.     Pro Am Class

  1. The following riders are eligible, but not required, to compete in the Pro Am class:
    • Top 20 ranked riders from previous year Pro Am class;
    • Top 5 ranked riders from previous year “A” classes; and
    • Top 5 ranked riders from previous year GNCC or WORCS Pro Am classes.

Pro Am riders who have earned 130 class points (Section J.2) in the current or previous season are eligible for the Pro class as an additional class. Pro Am Riders earning a Top 3 overall national ranking or finishing 1st place overall 5 or more events, in the Pro Am class the two previous consecutive years, are only eligible for the Pro class as an additional class. All other Pro Am riders are also eligible for the Open A only as an additional class. Otherwise, once a rider advances to the Pro Am class he is no longer eligible for an“A” class without petitioning AMA for re-classification.
  3. Motos will be 10 minutes plus 2 laps in length and will be held on Sunday.
  4. Class purse limited to top 3 overall positions.  No championship bonus will be paid.

2.     "A" Classes

  1. All "B" riders ranked in the top three of their class earning at least 50% of the points earned by the class champion in the previous year. Ranking is based on year-end series points and not the banquet awards.
  2. Riders that have an "A" ranking in any other motocross series. This applies to both AMA and non-AMA sanctioned events.
  3.  “A” class riders may only advance to the Pro Am or age division class.

3.     "B" Classes

  1. All "C" riders ranked in the top 3 of their class earning at least 50% of the points earned by the class champion in the previous year. Ranking is based on year-end series points and not the banquet awards.
  2. Riders with a "B" ranking in any other motocross series, AMA and non-AMA sanctioned events.
  3. “B” class riders may only advance to an “A” or age division class.

4.     "C" Classes:

Novice skill level riders and riders that do not otherwise qualify as an "A" or "B" level rider. Riders who receive or have ever received any type of OEM factory support in any class are not eligible for the "C" class.  “C” class riders may only advance to a “B” or age division class.

5.     Age:

For Amateur classes, riders must be 16 years or older on the date of the event in order to compete on any size machine in any class. For Youth classes, age is based on the rider's age on January 1, 2014. However, riders, including youth, who change age during the season, may stay in the class they started the year in, or may advance to the older division. Youth riders may advance to the next higher age class in the Youth Division prior to their age change, only if they will be eligible to do so at any time during the year.  However, once a rider moves to the next higher age class, they may not move back to the lower age class, per AMA rules.  Points accumulated in one class do not advance with the rider to another class.

6.     Advancement:

Amateur riders who participate in a higher classification (i.e. "A", "B" or "C") at any AMA or non-AMA local or national event will be considered as advanced to that higher classification and may not return to the lower class. Youth riders who compete in a higher age group may not return to their actual age group.  Youth riders may compete in a non-“A” designated Amateur class if age appropriate.

7.     Changing Classes:

A rider may petition to move to a lower classification based on class finishes. However, in order to do so, the rider must first petition his/her AMA district and/or the AMA/ATVA Motocross Manager for reclassification, and provide Event Organizer with a copy of the granted petition, prior to racing in the lower classification.

2.     If there are 21 or more riders in a class, the following program will be used:

a.     Riders will be divided into equal qualifier groups based on current point standings, with the higher ranked riders being assigned to different groups to avoid all top ranked riders competing in the same qualifying moto. (Example: 1st and 2nd place in points will be in separate groups; 3rd and 4th will be in separate groups, and so on. This does not mean that 1st and 3rd will be in the same group or 2nd and 4th will be in the same group. Computer will randomly place riders in separate groups.)

b.     All riders who do not advance from the qualifiers are eligible to compete in the last chance qualifier (LCQ) races.

c.     Rider advancement from qualifiers and LCQs are as follows:

20 entries or less 1 ALL 0 NA
21 - 36 Entries 2 8 1 4
37 - 40 Entries 2 8 2 2
41 - 56 Entries 4 4 2 2
57 - 76 Entries 4 4 3 2/1/1*
77 - 97 Entries 6 2 4 2
*Fastest LCQ transfers two (2) riders; other two transfer one (1) rider each.

 d.     Riders advancing from the qualifier motos will transfer their earned points according to their finishing position, i.e., a rider finishing in first place will receive one (1) point. Riders transferring from the LCQ will transfer their earned points according to the next finishing position, i.e., if eight riders transferred from each of the qualifier motos, the winner of the LCQ will receive a 9th place position, and so on.


1.     First moto or qualifier gate pics will be determined by computer draw. The second/final moto gate pics will be determined by first moto/qualifier finishing position, with the faster qualifier moto taking precedence.

2.     Riders must start each race with their tether cord properly affixed.

3.     Motos will be 5 Laps for Premiere Amateur classes; 4 Laps for all other classes, weather permitting.

4.     To accommodate the 50cc classes, a shortened or separate track may be used as necessary.

5.     Radios are permitted between pit crew members, but not with or between riders.

6.     No rider may ride in such a manner as to endanger life or limb of other riders, officials or the public. Riders will be penalized for the reckless operation of their machine or for running into an official.

7.     Unsportsmanlike conduct or the deliberate ramming, blocking, or intentional contact with another rider will result in a penalty.

8.     Team tactics include blocking, allowing another rider to pass in order to affect the outcome of the race. Riders involved will be penalized.


1.     Transponder

scoring is the official scoring process. The finish line will be marked and clearly visible.

2.     Race Finish:

The race officially ends for all contestants at the completion of the lap in which the checkered flag is displayed to the winner.  Should the checkered flag be displayed later than the official distance, the finishing order will be decided on the basis of the official advertised distance.

3.     Finish Position: 

Riders will be scored in order of finish and laps completed. It is not necessary to complete all laps in order to be scored. Any rider who makes at least one lap will get a finish position for that moto.

DNF: A rider who starts the race but does not make at least one lap will receive a "Did Not Finish" or DNF. A DNF results in moto points equal to the total number of riders in the class, but not less than 20.

DNS: A rider who does not report to staging will get a "Did Not Start/Stage". A DNS results in moto points equal to the total number of riders in the class, plus 30 points.

4.     Awards

Awards are given at the rate of 1 per every 3 riders, with a minimum of 10 awards per class.


The top 10 numbers for each class are reserved for the top 10 ranked riders from the previous year. A rider with an earned number has the option to reserve a different number, if available. To reserve a number, click HERE or go to www.atvmotocross.com for rider requirements.
