2021 Peugeot Tweet 125 SBC Technical Analysis & Specification Breakdown

Built around Peugeot's scooter motorcycle platform, the 2021 Peugeot Tweet 125 SBC pairs a 124.6 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 10.1 HP (7.3 kW) at 8,500 rpm while maximum torque reaches 9.2 Nm (6.8 lb-ft) at 7,000 rpm, transferring power to the rear wheel through belt final drive. With a specific output of 81.1 HP per liter and a 1,500 rpm working window between peak torque (7,000 rpm) and peak power (8,500 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 Tweet 125 SBC measures 109 kg (240 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.79 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 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 5.7-liter (1.5 US gal) fuel tank paired with a rated consumption of 2.8 L/100 km provides an estimated theoretical range of roughly 204 km (127 miles) between fill-ups, while factory top speed is listed at 90 km/h (56 mph).
