At the heart of the 2013 Honda Shadow Custom 400 custom - cruiser motorcycle, Honda features a 398 cc (24.3 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 30.8 HP (22.5 kW) at 7,000 rpm while maximum torque reaches 33 Nm (24.3 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 77.4 HP per liter and a 3,500 rpm working window between peak torque (3,500 rpm) and peak power (7,000 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 Custom 400 measures 255 kg (562 lbs) wet (curb), translating to a power-to-weight ratio of 0.12 HP/kg (8.28 kg per horsepower). Rider ergonomics and chassis geometry center around a 650 mm (25.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,655 mm (65.2 in) wheelbase engineered for planted straight-line stability. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 560 km (348 miles) between fill-ups.
