Engineered by Moto Guzzi for the naked motorcycle segment, the 2009 Moto Guzzi Breva 850 pairs a 877 cc (53.5 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 71.1 HP (51.9 kW) at 7,600 rpm while maximum torque reaches 66 Nm (48.7 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 81.1 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 Breva 850 measures 231 kg (509 lbs) dry, translating to a power-to-weight ratio of 0.31 HP/kg (3.25 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 1,495 mm (58.9 in) wheelbase engineered for balanced agility and highway composure. The 23-liter (6.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
