Technical Overview
2021 Vespa Primavera 50 S Technical Analysis & Specification Breakdown
At the heart of the 2021 Vespa Primavera 50 S scooter motorcycle, Vespa relies on a 49.9 cc (3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 3 HP (2.2 kW) at 7,500 rpm while maximum torque reaches 2.9 Nm (2.1 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.4 mm (1.5 x 1.6 inches).
Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,330 mm (52.4 in) wheelbase engineered for quick, flickable steering geometry. The 7.5-liter (2 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 300 km (186 miles) between fill-ups.
