Built around Moto Guzzi's naked motorcycle platform, the 2009 Moto Guzzi Griso 850 features a 877 cc (53.5 cu in) air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 75.1 HP (54.8 kW) at 7,600 rpm while maximum torque reaches 70 Nm (51.6 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 85.6 HP per liter and a 600 rpm working window between peak torque (7,000 rpm) and peak power (7,600 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 Griso 850 measures 227 kg (500 lbs) dry, translating to a power-to-weight ratio of 0.33 HP/kg (3.02 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,554 mm (61.2 in) wheelbase engineered for planted straight-line stability. The 17.2-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
