2009 Peugeot Sum Up Technical Analysis & Specification Breakdown
Positioned in Peugeot's scooter motorcycle lineup, the 2009 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 7.3 HP (5.3 kW), transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 58.6 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Sum Up measures 115 kg (254 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (15.75 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. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
