Engineered by Sym for the scooter motorcycle segment, the 2023 Sym Mio 50 utilizes a 49.5 cc (3 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 3 HP (2.2 kW) at 8,000 rpm while maximum torque reaches 3 Nm (2.2 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive.
On the scales, the Mio 50 measures 88 kg (194 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 1,250 mm (49.2 in) wheelbase engineered for quick, flickable steering geometry. The 5.2-liter (1.4 US gal) fuel tank paired with a rated consumption of 2.4 L/100 km provides an estimated theoretical range of roughly 217 km (135 miles) between fill-ups, while factory top speed is listed at 45 km/h (28 mph).
Within MotoLibrary's Sym archive, this model family spans 9 indexed model years from 2007 to 2025, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
