You cannot skip first moto and ride second moto to qualify. Adjustments on race day may be made to qualifying totals if divisions are not equal.

You may pack in front of the gate at the finals (no Tools or Farming). You will be disqualified if you pass or ride unsafe during a yellow flag.

Supercross Format:

Racers with more than one division:
Event staff will post the numbers of riders transferring to Main Event. If you place in transfer position from first moto you go directly to Main Event. If not, you ride in a Semi or LCQ and try to qualify for the Main Event. Results in Main Event are final results for this race; all qualifying positions will come from main.

Motocross Format:

Races with only one division of racers will be scored in a two-moto format with the second moto being the tiebreaker. Check your race schedule to determine how your race will be scored. Road to Mammoth qualifiers: You must race 2nd moto to qualify.
