At the heart of the 2013 Keeway Supershadow 250 custom - cruiser motorcycle, Keeway features a 248.9 cc (15.2 cu in) air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 19.4 HP (14.2 kW) at 8,750 rpm while maximum torque reaches 15 Nm (11.1 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 77.9 HP per liter and a 750 rpm working window between peak torque (8,000 rpm) and peak power (8,750 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Supershadow 250 measures 149 kg (328 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.68 kg per horsepower). Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,540 mm (60.6 in) wheelbase engineered for planted straight-line stability. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
