Engineered by Honda for the custom - cruiser motorcycle segment, the 2009 Honda Shadow Aero features a 745 cc (45.5 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 43 HP (31.4 kW) while maximum torque reaches 60.5 Nm (44.6 lb-ft), transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 57.7 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Shadow Aero measures 250.8 kg (553 lbs) wet (curb), translating to a power-to-weight ratio of 0.17 HP/kg (5.83 kg per horsepower). Rider ergonomics and chassis geometry center around a 658 mm (25.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,638 mm (64.5 in) wheelbase engineered for planted straight-line stability. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
