Engineered by Izuka for the custom - cruiser motorcycle segment, the 2025 Izuka K19 pairs a 198 cc (12.1 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 16.8 HP (12.2 kW) at 8,000 rpm while maximum torque reaches 16.5 Nm (12.2 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 84.8 HP per liter and a 1,500 rpm working window between peak torque (6,500 rpm) and peak power (8,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the K19 measures 160 kg (353 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.52 kg per horsepower). Rider ergonomics and chassis geometry center around a 710 mm (28 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,330 mm (52.4 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
