At the heart of the 2021 Zontes ZT125-G1 Scrambler sport motorcycle, Zontes 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 5-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-G1 Scrambler measures 160 kg (353 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.03 kg per horsepower). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,320 mm (52 in) wheelbase engineered for quick, flickable steering geometry. The 20-liter (5.3 US gal) fuel tank paired with a rated consumption of 2.8 L/100 km provides an estimated theoretical range of roughly 714 km (444 miles) between fill-ups, while factory top speed is listed at 119 km/h (74 mph).
