Road to Mammoth Qualifiers
Each racer will only have to qualify once per class. You may attend as many qualifiers as you wish, but you are only required to qualify once. You must race 2nd moto to qualify. All previously qualified riders are removed from that rounds’ results and the next rider(s) are moved up.

Each class has been given a certain percentage of riders that qualify directly into the 2023 Mammoth Motocross Championship. The closing date of qualified entries is May 17th; if you do not sign up by this deadline you forefit your qualified entry. There will be a small percentage of open entries available at MammothMotocross.com on May 22nd for those that did not qualify or sign up by the deadline. You must register in the class you qualified in at the qualifier; no transfers. Mammoth Motocross entries are non-transferrable and non-refundable. You MUST purchase practice.

Once a racer has qualified, they will be posted on the “I qualified” tab on 2xpromotions.com. Under “I Qualified”, select your class, and your name. The link will direct you to Regio to register for Mammoth Motocross.
