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.

The opening two rounds of the 2026 Superkarts! USA ProKart Challenge were held over the April 24-26 weekend at K1 Circuit. The Winchester, California facility welcomed the SKUSA regional program for rounds one and two of action to begin the six-round championship schedule. A total of 11 categories began the title chase for the 2026 season with five drivers able to leave the opening weekend with two wins toward their point total.

The 2026 season for the Superkarts! USA ProKart Challenge marks the 22nd edition of the organisation’s flagship regional program. The championship is coming off a strong 2025 season that featured increased numbers from the last several years, enjoying a schedule that featured three premier facilities. This year’s championship format features the same three circuits in a five-weekend, six-round, one-drop structure to welcome drivers from all across the western half of the United States.
