Engineered by Hartford for the sport motorcycle segment, the 2018 Hartford Sirius 223 utilizes a 223 cc (13.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 17.4 HP (12.7 kW) at 9,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 78 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 Sirius 223 measures 131 kg (289 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.53 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 3.57 L/100 km provides an estimated theoretical range of roughly 392 km (244 miles) between fill-ups.
