2007 Piaggio Liberty Catalyzed Technical Analysis & Specification Breakdown
Built around Piaggio's scooter motorcycle platform, the 2007 Piaggio Liberty Catalyzed utilizes a 49.4 cc (3 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 10 HP (7.3 kW) at 8,000 rpm while maximum torque reaches 10.2 Nm (7.5 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 40.0 x 39.3 mm (1.6 x 1.5 inches) with a 10.3:1 compression ratio.
On the scales, the Liberty Catalyzed measures 87 kg (192 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (8.7 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 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 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
