At the heart of the 2014 Sym Jet Sportx 50 scooter motorcycle, Sym utilizes a 49.4 cc (3 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 3.5 HP (2.5 kW) at 6,000 rpm while maximum torque reaches 4.2 Nm (3.1 lb-ft) at 5,500 rpm, transferring power to the rear wheel through belt final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.4 mm (1.5 x 1.6 inches).
On the scales, the Jet Sportx 50 measures 98 kg (216 lbs) dry. Rider ergonomics and chassis geometry center around a 1,275 mm (50.2 in) wheelbase engineered for quick, flickable steering geometry. The 6.3-liter (1.7 US gal) fuel tank paired with a rated consumption of 2.33 L/100 km provides an estimated theoretical range of roughly 270 km (168 miles) between fill-ups, while factory top speed is listed at 48 km/h (30 mph).
