Built around Herald's custom - cruiser motorcycle platform, the 2018 Herald Phantom 250 relies on a 249 cc (15.2 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 21 HP (15.3 kW) while maximum torque reaches 19.5 Nm (14.4 lb-ft), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 84.3 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 Phantom 250 measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.18 HP/kg (5.71 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 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.
