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.

The California ProKart Challenge traveled to the CalSpeed Karting Center for the lone double-round weekend of the 2022 season. The June 24-26 event at the Fontana, California facility hosted Rounds Three and Four of the Superkarts! USA regional championship program.

In just one week, the California ProKart Challenge returns to action and hosts the lone double-round weekend of the season. Competitors from all over the west coast will converge on the CalSpeed Karting Center facility in Fontana, California during the June 24-26 weekend for Rounds Three and Four of the Superkarts! USA regional program.

The California ProKart Challenge completed the second round of the 2022 season over the May 14-15 weekend at the Buttonwillow Raceway Park. It was the second straight event at the central California facility, with the opening event contested there in April. This time it would be in the clockwise direction around the 7/10-mile circuit. Another chunk of the $70,000 prize package for this season was awarded following the two days of action at Buttonwillow – with all but two drivers earning their first wins of the series this year.
