Technical Overview
2022 Piaggio Liberty 125 S Technical Analysis & Specification Breakdown
Engineered by Piaggio for the scooter motorcycle segment, the 2022 Piaggio Liberty 125 S relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 10.9 HP (7.9 kW) at 8,250 rpm while maximum torque reaches 10.8 Nm (7.9 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 87.9 HP per liter and a 1,750 rpm working window between peak torque (6,500 rpm) and peak power (8,250 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Liberty 125 S measures 99 kg (218 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.08 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 6-liter (1.6 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 240 km (149 miles) between fill-ups.
