2018 Zontes ZT250-S Technical Analysis & Specification Breakdown

Positioned in Zontes's sport motorcycle lineup, the 2018 Zontes ZT250-S pairs a 249 cc (15.2 cu in) oil & air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 24.1 HP (17.6 kW) at 8,000 rpm while maximum torque reaches 23 Nm (17 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 96.8 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 reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the ZT250-S measures 154 kg (340 lbs) wet (curb), translating to a power-to-weight ratio of 0.16 HP/kg (6.39 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,384 mm (54.5 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank paired with a rated consumption of 2.3 L/100 km provides an estimated theoretical range of roughly 478 km (297 miles) between fill-ups, while factory top speed is listed at 145 km/h (90 mph).
