Built around Yuki's scooter motorcycle platform, the 2022 Yuki 125i Coral pairs a 125 cc (7.6 cu in) single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 7.2 HP (5.3 kW) at 7,500 rpm while maximum torque reaches 9.5 Nm (7 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 57.6 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the 125i Coral measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (16.67 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 90 km/h (56 mph).
