The first event of the 2025 ProKart Challenge program was held on the February 28-March 2 weekend at the new K1 Circuit. The Winchester, California facility welcomed the Superkarts! USA regional program for a third time since opening its doors in August 2024. Rounds One and Two of the 2025 championship program kicked off with perfect racing weather to begin the 21st season of the series.

Debut event at anticipated facility welcomes big numbers in double weekend for Superkarts! USA regional program

 

The 2023 California ProKart Challenge came to a close on the September 22-24 weekend with the final two rounds contested at the Adams Motorsports Park in Riverside, CA. This was a revised series finale for the 19th championship season when Hurricane Hilary forced Round Five in August to be combined with Round Six. The new three-day weekend avoided weather issues, with perfect racing conditions for the drivers wrapping up the 2023 championship program.

The second event of the 2023 California ProKart Challenge saw teams and drivers return to the Buttonwillow Raceway Park over the May 6-7 weekend. Round Two of the Superkarts! USA regional program welcomed nearly 100 karters competing in seven categories around the 7/10-mile circuit in the clockwise direction. Perfect racing weather provided an amazing backdrop for the racing action over the two days.

The California ProKart Challenge completed the 2022 season over the October 1-2 weekend, signifying the end of two things. First, the sixth and final round of the Superkarts! USA regional program was contested at the CalSpeed Karting facility. Secondly, the Fontana, California facility hosted its final regional event prior to its closing later this year. CalSpeed has been the site to many Superkarts! USA events during its history, and the final chapter of that story helped to decide this year’s series champions. The backdrop was perfect with weather sunny and warm for the nearly 100 drivers competing over the two-day event on the ‘Classico’ layout.
