Engineered by Izuka for the sport motorcycle segment, the 2020 Izuka KL125 Advance relies on a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 6.5 HP (4.7 kW) at 8,000 rpm while maximum torque reaches 8.7 Nm (6.4 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 52 HP per liter and a 2,000 rpm working window between peak torque (6,000 rpm) and peak power (8,000 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the KL125 Advance measures 100 kg (220 lbs) wet (curb), translating to a power-to-weight ratio of 0.07 HP/kg (15.38 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. The 3.7-liter (1 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 80 km/h (50 mph).
