Positioned in Yamaha's scooter motorcycle lineup, the 2022 Yamaha Neo 125 UBS utilizes a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 9.8 HP (7.2 kW) at 8,000 rpm while maximum torque reaches 13.6 Nm (10 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 78.4 HP per liter and a 2,500 rpm working window between peak torque (5,500 rpm) and peak power (8,000 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 Neo 125 UBS measures 97 kg (214 lbs) wet (curb), translating to a power-to-weight ratio of 0.1 HP/kg (9.9 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,275 mm (50.2 in) wheelbase engineered for quick, flickable steering geometry. The 4.2-liter (1.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
