The California ProKart Challenge resumed the 2019 season with the first ever two-race weekend in series history. Rounds Two and Three were held at the CalSpeed Karting facility on June 8-9 following the opening event of 2019 in Buttonwillow in March. Approximately 150 competitors navigated the ‘Tecnico’ layout under challenging-hot weather conditions each day, totaling over 300 entries for the weekend. A number of drivers were able to double up in the win column on the weekend in their respective categories, closing out the first half of the 2019 championship chase for the California PKC. Racers also made history by setting new track records in all California PKC classes on their Evinco Tires, as well as winning incredible podium and raffle prizes.

Written by John Motley - National Tech Director   
Wednesday, 12 June 2019 11:03
As many of our competitors know, we took several fuel samples at the SKUSA Pro Tour SpringNationals event in Utah last month for further testing.

The following entrants’ fuels were tested:
  • Freddie Slater #727 X30 Junior
  • Ryan Norberg #N1 X30 Senior
  • Matt Johnson #517 X30 Master
In addition to SKUSA’s own analysis, we are happy to report that the three samples submitted to the VP Fuel’s head chemist were all determined not to have any additional ingredients beyond VP C12 and the allowed lubricants.

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.

A handful of drivers were able to repeat their victories on Saturday, solidifying their foothold in the title chase as the program looks toward the SummerNationals later this year.
