At the heart of the 2017 Keeway Silverblade 250 scooter motorcycle, Keeway features a 249.8 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 20.8 HP (15.2 kW) at 7,000 rpm while maximum torque reaches 23.4 Nm (17.3 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 83.3 HP per liter and a 1,000 rpm working window between peak torque (6,000 rpm) and peak power (7,000 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 Silverblade 250 measures 186 kg (410 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (8.94 kg per horsepower). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,490 mm (58.7 in) wheelbase engineered for balanced agility and highway composure. The 10.7-liter (2.8 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 115 km/h (71 mph).
