2021 Moto Guzzi V7 Stone Technical Analysis & Specification Breakdown
Positioned in Moto Guzzi's classic motorcycle lineup, the 2021 Moto Guzzi V7 Stone features a 850 cc (51.9 cu in) oil & air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 65 HP (47.4 kW) at 6,800 rpm while maximum torque reaches 73 Nm (53.8 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 76.5 HP per liter and a 1,800 rpm working window between peak torque (5,000 rpm) and peak power (6,800 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 V7 Stone measures 218 kg (481 lbs) wet (curb), translating to a power-to-weight ratio of 0.3 HP/kg (3.35 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, combined with a 1,463 mm (57.6 in) wheelbase engineered for balanced agility and highway composure. The 21-liter (5.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
