Engineered by Motomel for the naked motorcycle segment, the 2020 Motomel S6 250 relies on a 250 cc (15.3 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 23 HP (16.8 kW) at 7,500 rpm. With a specific output of 92 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the S6 250 measures 130 kg (287 lbs) dry, translating to a power-to-weight ratio of 0.18 HP/kg (5.65 kg per horsepower). The 22-liter (5.8 US gal) fuel tank paired with a rated consumption of 3.5 L/100 km provides an estimated theoretical range of roughly 629 km (391 miles) between fill-ups, while factory top speed is listed at 140 km/h (87 mph).
