Built around Lambretta's scooter motorcycle platform, the 2012 Lambretta LN151 relies on a 151 cc (9.2 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 10.3 HP (7.5 kW) at 7,500 rpm while maximum torque reaches 10.8 Nm (8 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 68.2 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 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 LN151 measures 111 kg (245 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.78 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
