At the heart of the 2014 Zontes ZT125-5A Monster sport motorcycle, Zontes features a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 11.7 HP (8.5 kW) at 8,000 rpm while maximum torque reaches 11.6 Nm (8.6 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 93.6 HP per liter and a 1,500 rpm working window between peak torque (6,500 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 ZT125-5A Monster measures 115 kg (254 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (9.83 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 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 17-liter (4.5 US gal) fuel tank paired with a rated consumption of 2.1 L/100 km provides an estimated theoretical range of roughly 810 km (503 miles) between fill-ups.
