Built around Vespa's scooter motorcycle platform, the 2012 Vespa LX 50 4V features a 49.4 cc (3 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 4.3 HP (3.1 kW) at 8,500 rpm while maximum torque reaches 3.5 Nm (2.6 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.8 mm (1.5 x 1.6 inches).
On the scales, the LX 50 4V measures 102.1 kg (225 lbs) dry. Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance.
