At the heart of the 2023 Cobra CX50SRX FWE minibike, cross motorcycle, Cobra utilizes a 50 cc (3.1 cu in) liquid-cooled single cylinder, two-stroke layout. 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 CX50SRX FWE measures 40 kg (88 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 1,038 mm (40.9 in) wheelbase engineered for quick, flickable steering geometry. The 2.8-liter (0.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
