At the heart of the 2020 Megelli Naked 250S naked motorcycle, Megelli utilizes a 249.5 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 27 HP (19.7 kW) at 9,000 rpm while maximum torque reaches 22.3 Nm (16.4 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 108.2 HP per liter and a 2,000 rpm working window between peak torque (7,000 rpm) and peak power (9,000 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the Naked 250S measures 135 kg (298 lbs) dry, translating to a power-to-weight ratio of 0.2 HP/kg (5 kg per horsepower). Rider ergonomics and chassis geometry center around a 765 mm (30.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
