Engineered by Vespa for the scooter motorcycle segment, the 2005 Vespa PX 150 features a 151 cc (9.2 cu in) air-cooled single cylinder, two-stroke configuration. Internal engine geometry specifies a bore and stroke of 57.0 x 58.0 mm (2.2 x 2.3 inches).
On the scales, the PX 150 measures 116 kg (256 lbs) wet (curb). 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, combined with a 1,260 mm (49.6 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
Within MotoLibrary's Vespa archive, this model family spans 6 indexed model years from 2005 to 2017, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
