At the heart of the 2012 Cobra CX50 BW minibike, cross motorcycle, Cobra relies on a 50 cc (3.1 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 39.0 x 41.7 mm (1.5 x 1.6 inches).
On the scales, the CX50 BW measures 43 kg (95 lbs) dry. Rider ergonomics and chassis geometry center around a 680 mm (26.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 990 mm (39 in) wheelbase engineered for quick, flickable steering geometry.
