About Cobra

Country of Origin: United States
Founder: Budd Maimone
Best Known For: High-performance 50cc/65cc kids’ motocross racers that win national titles

Company History

Cobra Moto reshaped youth motocross in the 1990s by proving that purpose-built race machinery for kids could be engineered with the same rigor as pro bikes. Founded by engineer Budd Maimone, the company targeted the intensely competitive 50cc and later 65cc classes that serve as the sport’s talent pipeline in the United States. Instead of detuned play bikes, Cobra delivered hand-on-the-pulse race tools: potent two-stroke engines, stiff yet lightweight frames, quality suspension, and ergonomics scaled for small riders. The results were immediate—Cobra machines began stacking up championships at events like Loretta Lynn’s Amateur Nationals, giving countless future pros their first taste of a green flag on equipment designed expressly for them. Beyond power, the brand’s secret sauce was development velocity. Feedback from families and regional tuners flowed into rapid updates, and parts support was structured so weekend warriors could keep bikes in the hunt with minimal downtime. That ecosystem—fast spares, setup guides, and a tight-knit paddock community—turned ownership into an education for both kids and parents. Cobra’s success also nudged larger manufacturers to take the youth segment more seriously, raising the technical baseline for everyone. Historically, the company’s impact reaches far beyond podium photos: it professionalized junior racing, taught young riders the language of chassis feel and jetting, and gave aspiring mechanics their first lessons in discipline and detail. For many American racers, the path to big bikes began with a yellow machine that felt like a real motorcycle, scaled perfectly to small hands, big dreams, and rutted tracks under summer heat.
