Built around Vespa's scooter motorcycle platform, the 2021 Vespa Primavera Sean Wotherspoon 50 relies on a 49.9 cc (3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 3.2 HP (2.3 kW) at 7,500 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 41.5 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 1,339 mm (52.7 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank paired with a rated consumption of 2.91 L/100 km provides an estimated theoretical range of roughly 275 km (171 miles) between fill-ups.
