1970 twin-engined Margay Cheetah go-kart

Margay Racing was founded in St. Louis, Missouri, in 1964 by Elmer Freber – it initially operated under the name Mar-Kart. The company’s early success came from a patented quick-change gearbox that allowed racers to swap gears more efficiently – a key advantage allowing racers to switch out gearboxes and match their ratios to the specific track where they would be racing.

Not long after this, Margay acquired the assets of King Kart, a move that instantly expanded its chassis lineup significantly and boosted its production capacity.

By the late 1960s, Margay had firmly established itself as one of America’s leading kart manufacturers. Its early “New Breed” chassis became a benchmark for US sprint racing, known for its good balance and tuneability.

Power comes from a matched pair of McCulloch MC-91/B two-stroke singles, each fitted with flat-back carburetors, starter pulleys, GEM-style mufflers, and centrifugal clutches feeding individual drive chains that power the rear axle.

The kart sits on staggered 5-inch Margay split-rim wheels with black spokes and polished lips, shod with racing slicks with white Bridgestone lettering. Stopping power comes from a rear-mounted Hurst Airheart hydraulic disc brake with a left-side master cylinder.
