The win total on the 2025 season increased by six for OTK Kart USA teams and drivers following the Superkarts! USA Pro Tour WinterNationals, held at the Speedsportz Racing Park on March 28-30. A record setting weekend at the New Caney, Texas facility featured over 300 entries in the eight categories competing. Over the two days of competition, a total of six wins, 16 podium results and 23 top five finishes were garnered by OTK Kart USA entries.

The headline Pro X30 division featured two OTK teams and two OTK drivers taking the top spot on the podium over the opening two rounds of the SKUSA Pro Tour. Six-time SKUSA Pro Tour champion Ryan Norberg (Rolison Performance Group / Kosmic) kicked off his drive to seven titles with a victory in Round One. He edged out fellow Floridian Austin Garrison (Speed Concepts Racing / CS55) after a great fight on Saturday. The following day, the two resumed their epic battle in another 20-lap duel, this time with Garrison securing the top spot for the victory with Norberg in the runner-up spot. Canadian Ayden Ingratta (Speed Concepts Racing / CS55) was a close third to sweep the podium while Pauly Massimino (Brandon Jarsocrak Racing / LN Racing Kart) put in a stellar drive to fourth in Round Two.

Alexander Vanchev (Rolison Performance Group / Kosmic) was able to double up on the weekend in the X30 Junior division. The 2025 SKUSA Winter Series title winner was able to win the Round One main event on Saturday by more than 10 seconds. Luca Popescu (Rolison Performance Group / Kosmic) was runner-up in his team debut with Tristan Murphy (Ryan Perry Motorsport / Tony Kart) helping to sweep the podium. Junior rookie Ashton Woon (Speed Concepts Racing / CS55) finished fourth in his class debut. Vanchev returned the following day to control the category in the main event, holding off a challenging Woon to the checkered flag. Murphy added another podium result in third with Canadian Nathan Dupuis (Nash Motorsportz / EOS) in the fifth position.

The action in the KA100 Junior category was heavily contested both days. The main event was cut short due to multiple red flag incidents, with Alexander Vanchev (Rolison Performance Group / Kosmic) earning the victory for his career first in the category. Tristan Murphy (Ryan Perry Motorsport / Tony Kart) joined him on the podium in third with Junior rookie Nico Orbezo (Iron Rock Motorsports / Tony Kart) placing fifth. The main event went the full distance on Sunday as Canadian Cole Medeiros (Racing Edge Motorsports / Kosmic) claimed his first SKUSA Pro Tour victory. Jose Alejandro Halphen (Rolison Performance Group / Kosmic) stood on the podium in third with Nathan Dupuis (Nash Motorsportz / EOS) making it two Canadians in the top five by finishing fifth.
