Positioned in Piaggio's scooter motorcycle lineup, the 2010 Piaggio XEvo 400 relies on a 399 cc (24.4 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 33 HP (24.1 kW) at 7,250 rpm while maximum torque reaches 36 Nm (26.6 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox. With a specific output of 82.7 HP per liter and a 1,750 rpm working window between peak torque (5,500 rpm) and peak power (7,250 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 XEvo 400 measures 198 kg (437 lbs) dry, translating to a power-to-weight ratio of 0.17 HP/kg (6 kg per horsepower). 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 1,540 mm (60.6 in) wheelbase engineered for planted straight-line stability. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 155 km/h (96 mph).
