The 2025 season concluded for the ProKart Challenge following the action on October 11-12 at the K1 Circuit. The Winchester, California, facility welcomed the Superkarts! USA regional program to close out its 21st season. A total of 161 entries battled around the 1.1-mile ‘Pro Track’ course for the sixth and final round of the 2025 championship.

The first event of the 2025 ProKart Challenge program was held on the February 28-March 2 weekend at the new K1 Circuit. The Winchester, California facility welcomed the Superkarts! USA regional program for a third time since opening its doors in August 2024. Rounds One and Two of the 2025 championship program kicked off with perfect racing weather to begin the 21st season of the series.

Debut event at anticipated facility welcomes big numbers in double weekend for Superkarts! USA regional program

 

The 19th season for the California ProKart Challenge has been put to the test as the program enters the second half of the championship chase. What was scheduled as a three-day, two-round race weekend at the Adams Motorsports Park in Riverside, California over August 18-20 became a shortened two-day, one-round event. Hurricane Hilary hit the southern California region on Sunday, forcing Superkarts! USA to postpone the Round Five action scheduled for that day. Round Four was contested on Saturday, with dry weather greeting the competitors at the historic Riverside, California facility.
