Positioned in Zontes's naked motorcycle lineup, the 2021 Zontes ZT125-U relies on a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 14.5 HP (10.6 kW) at 9,000 rpm while maximum torque reaches 13 Nm (9.6 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 116 HP per liter and a 2,000 rpm working window between peak torque (7,000 rpm) and peak power (9,000 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the ZT125-U measures 106 kg (234 lbs) dry, translating to a power-to-weight ratio of 0.14 HP/kg (7.31 kg per horsepower). Rider ergonomics and chassis geometry center around a 755 mm (29.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,320 mm (52 in) wheelbase engineered for quick, flickable steering geometry.
