Built around Yiben's scooter motorcycle platform, the 2014 Yiben YB250 ZKT utilizes a 249 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 18.1 HP (13.2 kW) at 6,500 rpm while maximum torque reaches 22.2 Nm (16.4 lb-ft) at 4,000 rpm, transferring power to the rear wheel through a automatic gearbox. With a specific output of 72.7 HP per liter and a 2,500 rpm working window between peak torque (4,000 rpm) and peak power (6,500 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 YB250 ZKT measures 207 kg (456 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.44 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,710 mm (67.3 in) wheelbase engineered for planted straight-line stability. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 120 km/h (75 mph).
