Positioned in Izuka's scooter motorcycle lineup, the 2010 Izuka YY150-21C pairs a 99.3 cc (6.1 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 7.5 HP (5.5 kW) at 7,500 rpm while maximum torque reaches 7.7 Nm (5.6 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 75.5 HP per liter and a 2,000 rpm working window between peak torque (5,500 rpm) and peak power (7,500 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 YY150-21C measures 112 kg (247 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (14.93 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,330 mm (52.4 in) wheelbase engineered for quick, flickable steering geometry.
