Built around Peugeot's scooter motorcycle platform, the 2018 Peugeot Belville 125 RS pairs a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 11.1 HP (8.1 kW) at 8,000 rpm while maximum torque reaches 10.7 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 88.8 HP per liter and a 1,500 rpm working window between peak torque (6,500 rpm) and peak power (8,000 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 Belville 125 RS measures 130 kg (287 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.71 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, combined with a 1,355 mm (53.3 in) wheelbase engineered for quick, flickable steering geometry. The 7.5-liter (2 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 300 km (186 miles) between fill-ups.
