What company owns and organizes the Rotax Max Challenge worldwide?

BRP-Rotax owns and organizes the Rotax Max Challenge worldwide.

The Rotax Max Challenge, usually abbreviated RMC, is a one-make karting series built around Rotax Max engines. BRP-Rotax establishes the sporting and technical framework, while authorized distributors deliver national and regional Challenge programs.

The series operates at club, national, continental, and international levels. Drivers can progress through local championships toward the annual Rotax Max Challenge Grand Finals, where competitors use controlled equipment intended to reduce differences between machines.

A common mix-up is confusing the organizer with kart or engine brands that appear in the competition. Sodi and Tony Kart are chassis manufacturers, while IAME produces competing kart engines; neither owns and organizes the worldwide RMC program. Rotax classes also vary by market, so local age groups and additional categories may differ.
