2007 Piaggio Liberty S 50 Technical Analysis & Specification Breakdown
At the heart of the 2007 Piaggio Liberty S 50 scooter motorcycle, Piaggio relies on a 49 cc (3 cu in) air-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 40.0 x 39.3 mm (1.6 x 1.5 inches) with a 9.9:1 compression ratio.
On the scales, the Liberty S 50 measures 83 kg (183 lbs) dry. Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,330 mm (52.4 in) wheelbase engineered for quick, flickable steering geometry. The 5-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
