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 traveling 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.

It was a historic SuperSunday to close out Superkarts! USA SuperNationals 28. For the first time in event history, postponed heat races and Last Chance Qualifiers were moved onto the final day of action due to the rain that continued to fall at the Las Vegas Motor Speedway on Saturday evening. A revised schedule for SuperSunday added in the final Pro class heat races, the opening ceremonies, and three LCQ races before the paddock rolled into the nine main events for the day. The weather was sunny, but it was certainly the coldest of the week and the added events pushed the action went to almost 7:00 pm local time, making for a fast-paced 12-hour day for officials and competitors. – Complete Coverage at the EKN Event Page.

The final races of the day took place under the lights around the temporary circuit outside Las Vegas Motor Speedway and featured 42 drivers taking the green flag. On the front row was former FIA Karting World Champion Viktor Gustafsson (Kart CRG USA) and Markus Kajak (Goodwood / Formula K), who saw his race end last year with contact in turn one while leading. At the drop of the green, Kajak grabbed the holeshot while Gustafsson struggled going into turn one, pushing wide while trying to make the turn. This collected Ricardo Longhi (PSL / Birelart) as the rest of the field powered around on the inside. Two drivers in contention were pushed wide in turn four as they tried to go three wide. Velocity Racing / Sodi Kart teammates Matheus Morgatto and Matteo Spirgel – starting fifth and seventh – saw their SuperSunday end after just four corners.

The final two days of the Superkarts! USA SuperNationals 28 will go down in history as one of the most unique events over its span of decades.

SuperSunday will feature, for the first time, four different heat races and their Last Chance Qualifiers before going into the main events to decide this year’s SuperNationals winners on Sunday.
