Built around Cobra's atv motorcycle platform, the 2010 Cobra ECX70 utilizes a 70 cc (4.3 cu in) liquid-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 67.1 HP (48.9 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 958.6 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the ECX70 measures 95.3 kg (210 lbs) dry, translating to a power-to-weight ratio of 0.7 HP/kg (1.42 kg per horsepower). Rider ergonomics and chassis geometry center around a 762 mm (30 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,067 mm (42 in) wheelbase engineered for quick, flickable steering geometry.
