Karting Solutions Group, the US distributor for BRP-Rotax karting products and home of the Race Rotax brand, is confirming a key detail for racers ahead of the 2026 SKUSA SuperNationals: Rotax engines from any country are eligible to compete in Senior MAX and Mini MAX at this year’s event, not just US sealed engines.

Karting Solutions Group (KSG), the US distributor for Rotax and home of the Race Rotax brand, today announces two developments for the 2026 season alongside TPK Promotions. For the first time, Rotax Mini MAX will join Senior MAX at the SKUSA SuperNationals in 2026, and the prize package for the Rotax MAX Challenge (RMC) Trophy Final has been expanded to give winners their choice of championship stage.

Rotax Karting is excited to announce a new chapter in its U.S. operations with the appointment of KSG as a key business partner. KSG will take over the responsibilities of both existing distributors – RTX and J3 –, bringing economic leverage, a deep passion for motorsport, and a unified network to elevate the Rotax karting business in the U.S. to an even higher level.
