Built around Izuka's sport motorcycle platform, the 2019 Izuka KL125 utilizes a 119.7 cc (7.3 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 8 HP (5.8 kW) at 7,500 rpm while maximum torque reaches 8.5 Nm (6.3 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 66.8 HP per liter and a 2,500 rpm working window between peak torque (5,000 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 KL125 measures 96 kg (212 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (12 kg per horsepower). Rider ergonomics and chassis geometry center around a 750 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,255 mm (49.4 in) wheelbase engineered for quick, flickable steering geometry.
