The opening round of the 2019 Superkarts! USA Pro Tour was completed in 100% wet conditions at the CalSpeed Karting facility. Rain was on and off all day in Fontana, California for the first day of action at the third edition of the WinterNationals with only a few glimpses of the sun breaking through the heavy clouds that surround the area and block off the mountain view. The 12 categories on hand battled the conditions and each other throughout the day to claim the steps on the podium to begin the chase for the championships on the right path.

The IAME SSE 175cc powerplant made its debut on the SKUSA Pro Tour with Pro Shifter 1 and Pro Shifter 2. A 24-driver field made up the inaugural event with Mathias Ramirez (PSL / Birel ART) setting fast time in qualifying. Jumping up to second on the final lap was Pro 2 driver Race Liberante (J3 / CompKart), making his first start with SKUSA since 2009. Liberante was able to grab the holeshot in the Prefinal, leading all 10 laps for the overall win and Pro 2 victory with Ramirez top driver in Pro 1. The opening lap was wild, including Liberante not able to get off the line clean. As they came around on the opening circuit, Mad Old Nut Racing’s Andrew Bujdoso (Croc Promotion) was into the lead. Bujdoso never put a wheel wrong throughout the 21 laps, scoring his first SKUSA Pro Tour victory. 2018 SKUSA Pro Tour champion AJ Myers (MONR / Croc) suffered issues in the Prefinal, driving his way from 17th on the grid to the second spot. Rory van der Steur (MRC / Tony Kart) completed the podium. Liberante fought back to fourth overall, winning the Pro 2 division with Max Hewitt (CRG Nordam) and Calvin Ming (MRC / Aluminos) joining him on the podium. Billy Musgrave (MRC / Aluminos) suffered a flat tire early in the Prefinal, driving his way from 20th to fourth in class, working past Kyle Wick (CRG Nordam) late in the race.

The 2019 season marks the 10th year of the Superkarts! USA Pro Tour. It all began in California with a trip to Sonoma for the inaugural event in 2010. Everything comes full circle as the Pro Tour kicks off the 10th season in the Golden State, making its first ever visit to the CalSpeed Karting facility in Fontana. The third edition of the WinterNationals moves cross-country from NOLA to outside the Auto Club Speedway, with 200 pre-registered drivers set to do battle on the newly revised ‘Grande’ circuit.

EKN Trackside – 2019 SKUSA Winter Series – Round 4 – Homestead

The final round of the Superkarts! USA Winter Series provided the intensity expected with championships on the line. The drivers had all put in a full day of wheel-to-wheel competition on Saturday running in the clockwise direction around the 12-turn AMR Homestead-Miami Motorplex Presented by MG Tires, and that experience brought more drivers into the mix on Sunday. The racing in X30 Senior boiled over during the final laps, and after the dust cleared and the penalties had been assessed, Rolison Performance Group’s Ryan Norberg emerged with his third win of the year and the Winter Series title. Rain tires were the right call for the Pro Shifter main and, in the tough conditions, Croc Promotion USA’s AJ Myers again emerged as the star, matching Norberg’s total of three wins to earn the title. Luca Mars was a front runner all weekend in X30 Junior and was in the fight for the Sunday victory, which came his way after the on-track winner was assessed a jump start penalty. All in all, the racing was very good to cap off the Winter Series and bodes well for what we’ll see on the 2019 SKUSA Pro Tour, which opens with the WinterNationals at CalSpeed Karting during the first weekend of March.

Weather played a role in Sunday’s storyline as a short burst of hard rain arrived just as the Briggs 206 driver hit the track for their main event. The rain would return later in the day, but it was not near as aggressive and lasted only long enough for National Director of Competition Joe Janowski to kept tires as ‘racers choice’. Read full story on eKartingNews.com

The expected excitement of the third round of the SKUSA Winter Series did not disappoint, as the racing was epic in a majority of the categories. Run in the reverse direction as the opening rounds in January, the 12-turn AMR Homestead-Miami Motorplex Presented by MG Tires presented a new challenge as multiple passing opportunities quickly emerged. Three-time SKUSA Pro Tour X30 champion Ryan Norberg cemented his reputation even further by recovering from contact-filled opening laps that shuffled him from pole to sixth, working back to the lead to score a stunning triumph. In Pro Shifter, MRC’s Billy Musgrave broke through for his first win after point lead AJ Myers (Croc Promotion USA) suffered a rear sprocket failure while leading in the main. The third storyline centered on the masterful performance by Canadian Mackenzie Clark (Prime Powerteam / BirelART), who positioned himself in the lead trio in X30 Junior and then managed the race with precision, moving to the lead in the late-going to score his maiden national level victory.
