At the heart of the 2025 Peugeot Speedfight4 50 scooter motorcycle, Peugeot relies on a 49.9 cc (3 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 3.9 HP (2.8 kW) at 8,000 rpm while maximum torque reaches 3 Nm (2.2 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 39.8 x 41.0 mm (1.6 x 1.6 inches).
On the scales, the Speedfight4 50 measures 97 kg (214 lbs) wet (curb). 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 1,256 mm (49.4 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 45 km/h (28 mph).
