Positioned in Vespa's scooter motorcycle lineup, the 2021 Vespa Sprint 150 features a 155 cc (9.5 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12.5 HP (9.1 kW) at 7,750 rpm while maximum torque reaches 12.4 Nm (9.1 lb-ft) at 6,750 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 80.6 HP per liter and a 1,000 rpm working window between peak torque (6,750 rpm) and peak power (7,750 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
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 1,340 mm (52.8 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank paired with a rated consumption of 2.72 L/100 km provides an estimated theoretical range of roughly 294 km (183 miles) between fill-ups.
