2005 Piaggio B 500 Technical Analysis & Specification Breakdown

Positioned in Piaggio's scooter motorcycle lineup, the 2005 Piaggio B 500 relies on a 460 cc (28.1 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 39 HP (28.5 kW) at 7,500 rpm while maximum torque reaches 43 Nm (31.7 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox. With a specific output of 84.8 HP per liter and a 2,000 rpm working window between peak torque (5,500 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 B 500 measures 213 kg (470 lbs) wet (curb), translating to a power-to-weight ratio of 0.18 HP/kg (5.46 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,540 mm (60.6 in) wheelbase engineered for planted straight-line stability. The 13.2-liter (3.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 161 km/h (100 mph).
