The first quarter of the 2021 season is now in the books this calendar year. Back in January, OTK race teams, kart shops and competitors from all over the western half of the United States began competing for Challenge of the Americas victories and championships. The series finale was held at the Sonoma Raceway in Sonoma, California on the March 26-28 weekend. Beautiful clear, sunny skies greeted over 100 competitors on the weekend, with a large majority of these races utilizing the quality and consistency of OTK products. In total, seven victories were earned by drivers on OTK chassis, extending to 20 podium finishes and 34 top-five results over the two days in six of the categories run in the COTA program. When the final checkered flag had waved on Sunday, OTK took home five of the series’ championships.

A total of two wins and a two championship came for OTK in the single-speed Masters divisions. Derek Wang (EOS) made history, becoming the first three-time champion in the 14-year history of the Challenge while also completing them in a row. Wang overcame a DNF in Round Five on Saturday to sweep the action on Sunday, earning his fourth victory of the year to clinch the title. OTK earned four of the top-five in Saturday’s main event, led by Tim Meyer (HRT / EOS). Local driver Georgious Georgiou (Tony Kart) stood on the podium with David Pergande (JH Motorsports / Tony Kart) in fourth and Billy Cleavelin (SpeedSense Motorsports / Tony Kart) in fifth. Sunday’s race saw the order shuffle around behind Wang with Georgiou up to second and Meyer down to third. Pergande ended the year matching his Saturday finish of fourth. Joining Wang on the championship podium was Meyer, placing third in the final standings.

Like Wang, Mike Smith (VMI / EOS) secured a championship with a victory in the final round. Smith led the way on Saturday for OTK drivers, placing second in the main event with Tim Meyer (HRT / EOS) in fourth and Dana Estes (Ryan Perry Motorsport / Tony Kart) in fifth. Sunday saw Smith come from behind, securing the lead in the second half of the race and going on to earn his first victory of the season. The win locked up his first Challenge championship. Brian Phillipsen (MMK / Redspeed) stood on the podium in third with Estes up to fourth. It was a clean OTK sweep of the top-three in the championship chase led by Smith, with Meyer in second and Phillipsen earning the third most points in the best-of-five format.
