Engineered by Gilera for the scooter motorcycle segment, the 2009 Gilera GP800 pairs a 839.3 cc (51.2 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 65.5 HP (47.8 kW) at 7,250 rpm while maximum torque reaches 76.4 Nm (56.4 lb-ft) at 5,750 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 78 HP per liter and a 1,500 rpm working window between peak torque (5,750 rpm) and peak power (7,250 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 GP800 measures 262 kg (578 lbs) wet (curb), translating to a power-to-weight ratio of 0.25 HP/kg (4 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 1,593 mm (62.7 in) wheelbase engineered for planted straight-line stability. The 18.5-liter (4.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
