License Requirements 

All Rotax racers are eligible to hold US Rotax License/Membership.  For participation in National Level events, i.e. US Grand Nationals, only US Citizens and Permanent Residents are eligible.   

Definition of permanent resident by the United States government;

A non-U.S. citizen who has been given permission to make his or her permanent home in the United States. If you acquire permanent residence, you will be issued a green card to prove it. The terms permanent resident and "green card holder" mean exactly the same thing. You cannot be a permanent resident without a green card and you cannot have a green card without being a permanent resident. As a permanent resident, you may travel as much as you like, but your place of residence must be the United States and you must keep that residence on a permanent basis. If you leave the United States and stay away for more than a year, you risk losing your green card. A link to the website with the above definition can be found below.

It is our goal to welcome everyone into the Rotax program.  The spots available to the World Finals will be open to US Citizens and permanent residentsonly.  We encourage all local and regional series to allow visitors working in our country to join the US Club Rotax and participate in their series whenever possible. 

Additional requirements 

Kart Numbering: For any event the first competitor to enter has the choice of numbers.  Local and regional series may set up a system for securing numbers by competitors for their respective series.  Approved numbers are 2 or 3 digits, letters are not recognized.  USRMC reserves the right to assign numbers to competitors that do not provide acceptable numbers for their entry thru the normal registration process. It is not the responsibility of event organizers to supply the required numbers for any entry. 

Transponders: Each competitor is required to bring a transponder to each event.  Transponder presentation will be considered part of Scrutineering.  Transponder renting to racers will not be a responsibility of event organizers or the host track/club.   It is the responsibility of the racer and his crew to insure the competitor’s transponder is charged and on the kart each time it enters the track during any official portion of the event. 

Spec Gear Mini Max class: The recognized spec gear nationally is 13 x 82 with a local option of 12 x 76,   The official National Spec Gear will remain 13 x 82 and this is the gear that will be assigned for the USRMC Grand Nationals.

If a series elects to use the optional 12x76 spec gear it must be announced prior to the beginning of the event in the form of a written supplemental regulation.  This supplemental regulation must be posted on series website at least 7 days in advance of the event.  It must also be placed on the official event posting board and reviewed at the drivers briefing.  All competitors in the class must use the same gear.
