HILLSDALE, Mich., (Oct. 12 , 2010) - American-made Cobra Motorcycles' Chase Sexton (Illinois) and Parker Mashburn (Texas) were the big winners at this past week's 16th annual Branson USA National Motocross Championships, one of the country's biggest races of the fall season, drawing a reported 1,100 amateur MX competitors to the banks of the James River in the southwestern corner of Missouri.Sexton, aboard Cobra's crate-to-podium CX65, was on fire in the 65cc 9-11 Modified and 65cc Open Through 11 classes, winning three out of four motos - including a Mod class sweep on his JMS/MXT-prepped bike - and the all-important second moto in the all-star Open class to secure that overall victory. And Mashburn was equally impressive, racking up two overall championships on his EBR Cobra King 50 in the 50cc Senior PW classes (Stock 7-8 and Mod 7-8)."It's definitely cause for celebration at Cobra HQ anytime we can pull off a win versus the highly-funded foreign factory bikes," said Sean Hilbert, President of Michigan-based Cobra Motorcycles. "Congrats to Chase, Parker and the rest of the Cobra kids that competed this past week at Branson. Hit the school books hard and we'll see you in just over a month here at the Mini Os."
