Engineered by Honda for the custom - cruiser motorcycle segment, the 2018 Honda Shadow Aero ABS features a 745 cc (45.5 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 46 HP (33.6 kW) at 5,500 rpm while maximum torque reaches 64 Nm (47.2 lb-ft) at 3,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 61.7 HP per liter and a 2,000 rpm working window between peak torque (3,500 rpm) and peak power (5,500 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 Shadow Aero ABS measures 259.9 kg (573 lbs) wet (curb), translating to a power-to-weight ratio of 0.18 HP/kg (5.65 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 paired with a rated consumption of 4.2 L/100 km provides an estimated theoretical range of roughly 333 km (207 miles) between fill-ups.
