At the heart of the 2019 Herald Cafe 400 allround motorcycle, Herald utilizes a 397 cc (24.2 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 27 HP (19.7 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 68 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Cafe 400 measures 165 kg (364 lbs) dry, translating to a power-to-weight ratio of 0.16 HP/kg (6.11 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
