Engineered by Harley-Davidson for the allround motorcycle segment, the 2024 Harley-Davidson X440 relies on a 440 cc (26.9 cu in) oil & air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 27 HP (19.7 kW) at 6,000 rpm while maximum torque reaches 38 Nm (28 lb-ft) at 4,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 61.4 HP per liter and a 2,000 rpm working window between peak torque (4,000 rpm) and peak power (6,000 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 X440 measures 190.5 kg (420 lbs) wet (curb), translating to a power-to-weight ratio of 0.14 HP/kg (7.06 kg per horsepower). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,418 mm (55.8 in) wheelbase engineered for quick, flickable steering geometry. The 13.5-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
