US Rotax MAX Challenge

The US Rotax MAX Challenge is a nation-wide program of competitive racing events using Rotax engines and products.

The Rotax MAX Challenge (RMC) is a professional kart racing series established, owned and organized by BRP-Powertrain and its distributors. The RMC is a "one-make-engine" formula: only Rotax kart engines are allowed. There are seven different race classes: 125 Micro MAX, 125 Mini MAX, 125 Junior MAX, 125 Senior MAX, 125 Masters MAX, 125 MAX DD2 and 125 MAX DD2 Masters.

The RMC utilizes Rotax kart engines which are checked and sealed (for equal performance). The sealing is done by authorized distributors or their authorized service centers.

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.

Authorized distributors of Rotax kart products offer their customers a national RMC program according to the "Rotax Sporting and Technical Regulations” defined by BRP-Powertrain. This results in a fair competition between semi-professional kart racers that share the same interests.
