Positioned in Vespa's scooter motorcycle lineup, the 2011 Vespa PX 150 features a 149.6 cc (9.1 cu in) air-cooled single cylinder, two-stroke configuration. Internal engine geometry specifies a bore and stroke of 57.8 x 57.0 mm (2.3 x 2.2 inches).
On the scales, the PX 150 measures 97 kg (214 lbs) dry. Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 87 km/h (54 mph).
