TEMECULA, CA – The 21st season of the ProKart Challenge concluded this past October, completing the five events with six rounds of competition for the Superkarts! USA regional program. Eleven different class champions were crowned following the action at the K1 Circuit finale event.
The 2025 ProKart Challenge was a best five of six championship format, visiting three facilities over five weekends. K1 Circuit hosted the opening two rounds in the first weekend of March before travelling to the new Spring Mountain Karting Complex in April for its debut on the PKC schedule. The series returned to K1 Circuit in June for Round Four before making a trip north to Sonoma Raceway in late August – for the first time in Superkarts! USA history since 2017. K1 Circuit hosted the series finale in October, helping to decide this year’s ProKart Challenge champions.
Keagan Kaminski was able to win for a second straight year in the Formula Works KA100 Senior championship. The 2024 title came without a victory, while Kaminski won five straight to clinch the 2025 crown prior to the series finale. The advantage was 187 points, with four-time podium finisher Jackson Menchu ending up second in the standings. Round Six winner Shea Aldrich completed the season third in the championship.
The SuperSpeed Bearings KA100 Junior championship was also won for a second straight year by one driver, as Matthew Cagle claimed the title once again. Similar to Kaminski, Cagle won in 2024 without a victory; however, he came through for victory twice in 2025, standing on the podium five straight races to defend his championship. Sebastian Hauser, a winner at Round Two, was second in the final standings, trailing Cagle by 130 points. Canadian Nathan Dupuis earned three podium finishes on the season, including a win in Round Five, to finish third in title chase.
Luis Martinez added his name to the list of champions in the HRT Driver Development Mini Swift category. A string of five podium finishes, including three wins in total, helped Martinez to claim the championship by 169 points after finishing last year’s standings in seventh. Nathan Ramirez also improved on his finishing position from 2024, moving up from fifth to second to close out 2025. Ramirez had three podium finishes to his credit over the six rounds of racing. 2024 PKC Micro Swift champion Hudson Hidalgo finished inside the top three a total of three times in his five starts to claim the third step of the championship podium in his first year in the Mini Swift category.
Aidan Go brought his win total to three at the end of the year in the Sanner Racing Micro Swift class to help him earn the 2025 championship. Go, who finished second in last year’s standings, claimed victory in the final two rounds of 2025 to earn the championship by just 40 points over Matthew Paciulli. Two wins with a total of five podium results helped to put Paciulli second in the standings for his first full season at PKC. Lyon McPhail drove to two podium results over the six rounds to end up third in his first season.
Five podium finishes, including two wins, put Billy Musgrave at the top of the class in the Precision Works Racing Engines Pro Shifter championship. Musgrave, a multi-time PKC champion and now a six-time SKUSA SuperNationals winner, continues to add to his impressive career. Keawn Tandon had three podium results on the year to finish second, with NorCal driver Anthony Freese finishing third in the final standings with one podium result on the season.
