2011 Vespa S 50 4V Technical Analysis & Specification Breakdown

Positioned in Vespa's scooter motorcycle lineup, the 2011 Vespa S 50 4V pairs a 49.4 cc (3 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, maximum torque reaches 3.5 Nm (2.6 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox. Internal engine geometry specifies a bore and stroke of 39.0 x 41.8 mm (1.5 x 1.6 inches).

On the scales, the S 50 4V measures 96 kg (212 lbs) dry. Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,295 mm (51 in) wheelbase engineered for quick, flickable steering geometry. The 8.6-liter (2.3 US gal) fuel tank paired with a rated consumption of 2.69 L/100 km provides an estimated theoretical range of roughly 320 km (199 miles) between fill-ups, while factory top speed is listed at 63 km/h (39 mph).
