2012 Vespa S 150 i.e. Technical Analysis & Specification Breakdown

Built around Vespa's scooter motorcycle platform, the 2012 Vespa S 150 i.e. 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 i.e. 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. The 8.2-liter (2.2 US gal) fuel tank paired with a rated consumption of 3.24 L/100 km provides an estimated theoretical range of roughly 253 km (157 miles) between fill-ups, while factory top speed is listed at 95 km/h (59 mph).
