Positioned in Honda's custom - cruiser motorcycle lineup, the 2018 Honda Shadow Aero pairs a 745 cc (45.5 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. 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 254 kg (560 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. 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.
