Positioned in Hartford's minibike, sport motorcycle lineup, the 2023 Hartford Mini 150 pairs a 149 cc (9.1 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 18.1 HP (13.2 kW) at 8,300 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 121.5 HP per liter, 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 Mini 150 measures 115 kg (254 lbs) dry, translating to a power-to-weight ratio of 0.16 HP/kg (6.35 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,160 mm (45.7 in) wheelbase engineered for quick, flickable steering geometry. The 12-liter (3.2 US gal) fuel tank paired with a rated consumption of 3.57 L/100 km provides an estimated theoretical range of roughly 336 km (209 miles) between fill-ups.
