2023 Hanway B40 Technical Analysis & Specification Breakdown

At the heart of the 2023 Hanway B40 custom - cruiser motorcycle, Hanway pairs a 389 cc (23.7 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 37.6 HP (27.4 kW) at 8,500 rpm while maximum torque reaches 36 Nm (26.6 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 96.7 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the B40 measures 185 kg (408 lbs) dry, translating to a power-to-weight ratio of 0.2 HP/kg (4.92 kg per horsepower). Rider ergonomics and chassis geometry center around a 640 mm (25.2 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,518 mm (59.8 in) wheelbase engineered for balanced agility and highway composure. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
