The California ProKart Challenge is preparing for a return to the track after two months off following the 2019 opening event at Buttonwillow. The flagship regional program for Superkarts! USA returns to the site of the 2019 SKUSA Pro Tour WinterNationals with a unique and first ever dual-round weekend, as Rounds Two and Three will be contested on the June 7-9 weekend at the CalSpeed Karting facility. Competitors will compete in a similar format to the Pro Tour, with optional practice on Friday, and then two separate race days on Saturday and Sunday. The track layout will be different from the March weekend, with competitors set to battle around the ‘Tecnico’ circuit. The weather is forecasted to be perfect racing weather, and the turnout is expected to be the biggest of the season.

The 2019 California ProKart Challenge kicked off its season at Buttonwillow Raceway Park on March 30-31. A number of drivers swept the action for the opening round, including reigning SKUSA SuperNationals winner Billy Musgrave. The five-time California PKC champion went unchallenged in the Croc Promotion USA/Mad Old Nut Pro Shifter category. Add in Micah Hendricks in the Musgrave Racing Company Pro Shifter 2 division, John Crow in the Alpinestars G1 Gladiator class, Nick George in S4 Master Stock Moto, Brett Harrelson in Bell Helmets S4 Super Master Stock Moto, Stuart Hayner in AiM Sports X30 Super Master, and defending IAME USA West Micro Swift champion Graham Trammell. All seven will attempt to continue their streak in the P1 position through the double race weekend in Fontana.

The 2019 California ProKart Challenge began its season with the opening round held at the Buttonwillow Raceway Park in Buttonwillow, California under welcome sunny skies. The March 30-31 event was the first of the 15-year celebration for the Superkarts! USA regional program, and marked a new change in format that also seemed to be a big hit with both new and seasoned California PKC racers. The action was held on Saturday-Sunday and featured the new Qualifying-Prefinal-Final structure. Portions of the $120,000, the largest prize package in series history, were handed out on the weekend as 120 competitors contested the first of six rounds toward the championships in the 16 categories.

The 15th season of the California ProKart Challenge will be celebrated throughout 2019, with the program set to begin this weekend. The flagship regional program for Superkarts! USA opens the racing calendar at Buttonwillow Raceway Park in Buttonwillow, California on March 30-31. The 2019 season will be one for the record books, with a revised weekend format, a condensed six-round championship with a five-event schedule, and the largest prize purse ever offered up by the program.

Dating back to its origins during the 2005 season, the California ProKart Challenge was traditionally a two-day event held on Friday and Saturday of the weekend. New for the 2019 season is the shift to a Saturday-Sunday approach with an adjustment in the daily schedule format as well. Official practice begins on Saturday morning, with all categories being provided five rounds of practice ahead of Qualifying, which will be conducted at the end of the day. Sunday’s schedule will include a warm-up, with the Prefinal and Final to conclude each round early enough to allow competitors the opportunity to travel home before the sun sets. This new approach was formulated using the input and feedback from SKUSA’s racers and families.
