The RMC follows a "one-make-engine" formula: onlyRotax Max kart engines are allowed. The success in the competition is mainly up to the skills of the driver and that driver's experience in the set up of the engine and the chassis.
Three race classes are recognized for international competition:
| Class | Power | Age |
|---|---|---|
| Junior MAX | 17 kW (23 hp) | 10–16 years of age |
| MAX | 22 kW (30 hp) | 13 years and older |
| DD2, 2 speed shifter class | 25 kW (34 hp) | 13 years and older |
Competition at the national level can include additional classes at the discretion of each national RMC. For example, the US RMC includes the following classes:
| Class | Power | Age |
|---|---|---|
| Micro MAX | 6 kW (8 hp) | 7–10 years of age |
| Mini MAX | 11 kW (15 hp) | 9–12 years of age |
| Junior MAX | 17 kW (23 hp) | 13–16 years of age |
| Senior MAX | 22 kW (30 hp) | 15 years and older |
| Masters MAX | 22 kW (30 hp) | 32 years and older |
| DD2 MAX, 2 speed shifter class | 25 kW (34 hp) | Senior: 15 years and older/ Masters: 32 years and older |
Authorised distributors of Rotax kart products offer their customers a national RMC programme according to the “Rotax Sporting and Technical Regulations” defined by BRP-Rotax. This results in a fair competition between kart racers that share the same interests.

In 2003, the Rotax Max Challenge Grand Finals moved toEgypt. That year, the Junior category was introduced. It was also the company's first time cooperating with a chassis manufacturer in order to supply comparable karts to the competitors. The Junior category raced on a 'single make' chassis supplied byCRG while the seniors raced on their private chassis. This move increased the number of participants to almost 100, representing close to 40 countries.
