At the heart of the 2017 Vespa PX 150 scooter motorcycle, Vespa pairs a 150 cc (9.2 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. 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 106 kg (234 lbs) wet (curb). 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, 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, while factory top speed is listed at 87 km/h (54 mph).
