At the heart of the 2011 Honda Shadow Aero custom - cruiser motorcycle, Honda features a 745 cc (45.5 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, maximum torque reaches 79 Nm (58.3 lb-ft), transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. Internal engine geometry specifies a bore and stroke of 79.0 x 76.0 mm (3.1 x 3.0 inches) with a 9.6:1 compression ratio.
On the scales, the Shadow Aero measures 250.8 kg (553 lbs) wet (curb). 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.
