Engineered by Yamaha for the scooter motorcycle segment, the 2022 Yamaha Zuma 125 pairs a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 9 HP (6.6 kW), transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 72 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Zuma 125 measures 127.9 kg (282 lbs) wet (curb), translating to a power-to-weight ratio of 0.07 HP/kg (14.21 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,306 mm (51.4 in) wheelbase engineered for quick, flickable steering geometry. The 6.43-liter (1.7 US gal) fuel tank paired with a rated consumption of 2.33 L/100 km provides an estimated theoretical range of roughly 276 km (171 miles) between fill-ups.
