At the heart of the 2019 Moto Guzzi MGX-21 custom - cruiser motorcycle, Moto Guzzi features a 1380 cc (84.2 cu in) oil & air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 96 HP (70.1 kW) at 6,500 rpm while maximum torque reaches 121 Nm (89.2 lb-ft) at 3,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 69.6 HP per liter and a 3,500 rpm working window between peak torque (3,000 rpm) and peak power (6,500 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 MGX-21 measures 356 kg (785 lbs) wet (curb), translating to a power-to-weight ratio of 0.27 HP/kg (3.71 kg per horsepower). Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,700 mm (66.9 in) wheelbase engineered for planted straight-line stability. The 20.5-liter (5.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
