Positioned in Keeway's custom - cruiser motorcycle lineup, the 2017 Keeway Blackster 250 pairs a 248.9 cc (15.2 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 19 HP (13.9 kW) at 8,500 rpm while maximum torque reaches 18.7 Nm (13.8 lb-ft) at 5,750 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 76.3 HP per liter and a 2,750 rpm working window between peak torque (5,750 rpm) and peak power (8,500 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 Blackster 250 measures 170 kg (375 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (8.95 kg per horsepower). Rider ergonomics and chassis geometry center around a 688 mm (27.1 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 13.5-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 110 km/h (68 mph).
