Engineered by Lambretta for the scooter motorcycle segment, the 2013 Lambretta LJ 50 relies on a 49.5 cc (3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 4.3 HP (3.1 kW) at 8,000 rpm while maximum torque reaches 4.2 Nm (3.1 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 38.0 x 43.5 mm (1.5 x 1.7 inches) with a 11.0:1 compression ratio.
On the scales, the LJ 50 measures 87 kg (192 lbs) dry. Rider ergonomics and chassis geometry center around a 750 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops.
