Engineered by Piaggio for the scooter motorcycle segment, the 2011 Piaggio MP3 LT 400 relies on a 398 cc (24.3 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 34 HP (24.8 kW) at 7,500 rpm while maximum torque reaches 37 Nm (27.3 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 85.4 HP per liter and a 2,500 rpm working window between peak torque (5,000 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 MP3 LT 400 measures 244 kg (538 lbs) wet (curb), translating to a power-to-weight ratio of 0.14 HP/kg (7.18 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 142 km/h (88 mph).
