Technical Overview
2005 Piaggio Liberty 50 Catalyzed Technical Analysis & Specification Breakdown
At the heart of the 2005 Piaggio Liberty 50 Catalyzed scooter motorcycle, Piaggio utilizes a 49.4 cc (3 cu in) air-cooled single cylinder, two-stroke layout. 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 50 Catalyzed measures 87 kg (192 lbs) dry. 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 paired with a rated consumption of 2.13 L/100 km provides an estimated theoretical range of roughly 282 km (175 miles) between fill-ups.
