S 150

2010 Vespa S 150 Technical Analysis & Specification Breakdown

Positioned in Vespa's scooter motorcycle lineup, the 2010 Vespa S 150 relies on a 150 cc (9.2 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 11.7 HP (8.5 kW) at 7,750 rpm while maximum torque reaches 11.5 Nm (8.5 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 78 HP per liter and a 1,750 rpm working window between peak torque (6,000 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.

On the scales, the S 150 measures 110 kg (243 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.4 kg per horsepower). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry.
