2010 Peugeot Sum Up Technical Analysis & Specification Breakdown

Built around Peugeot's scooter motorcycle platform, the 2010 Peugeot Sum Up features a 124.6 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 8.3 HP (6.1 kW) at 7,500 rpm while maximum torque reaches 7.6 Nm (5.6 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 66.6 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 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 Sum Up measures 115 kg (254 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (13.86 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 1,370 mm (53.9 in) wheelbase engineered for quick, flickable steering geometry. The 6.5-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
