The 2025 season concluded for the ProKart Challenge following the action on October 11-12 at the K1 Circuit. The Winchester, California, facility welcomed the Superkarts! USA regional program to close out its 21st season. A total of 161 entries battled around the 1.1-mile ‘Pro Track’ course for the sixth and final round of the 2025 championship.

Speed Concepts Racing has established itself as one of the top karting teams in North America with a resume that boasts multiple wins and championships over the last few seasons. The 2025 campaign was no different as the team added new racers to their roster throughout the year. As the third quarter comes to a close, the team is happy to announce the addition of Cash Perkins to the driver roster in the Senior ranks for the remainder of the 2025 season and into 2026.

The sixth and final round of the Superkarts! USA California ProKart Challenge was held over the September 28-29 weekend, returning to the K1 Circuit. The Winchester, California facility sparked up the entry total once again, surpassing the 150-mark for 11 classes in competition. Perfect weather greeted the teams and drivers completing the 20th season for the championship program.

With rain overnight and the threat of more rain in the forecast throughout the day, RMC Winter Trophy competitors descended on the Orlando Kart Center (OKC) for the final time in 2024. With race wins, championships, and tickets to the RMC Grand Finals on the line, the wheel-to-wheel action commenced with prefinals for all classes with grids set from Friday’s qualifying session before the afternoon made way for the main events on Championship Sunday.

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.
