Rotax MAX Challenge Rules and Regulations
The RMC is authorized and sanctioned by CIK/FIA, using Rotax kart engines which are checked and sealed (for equal performance).
By following the "Rotax Sporting and Technical Regulations" of the Rotax MAX Challenge and by using a mandatory type of tire (MOJO), the success in the competition is mainly up to the skills of the driver and his/her experience in the set up of the combination of the engine and the chassis.
Here you can find the most current Sporting and Technical Regulations from BRP-Rotax. These are the rules that are the standard of the Rotax Max Challenge and are used in over 67 different countries.
