Built around Jonway's allround motorcycle platform, the 2012 Jonway YY250X-8 relies on a 249 cc (15.2 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 19.4 HP (14.2 kW) at 8,500 rpm while maximum torque reaches 17.5 Nm (12.9 lb-ft) at 6,000 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 77.9 HP per liter and a 2,500 rpm working window between peak torque (6,000 rpm) and peak power (8,500 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 YY250X-8 measures 162 kg (357 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.35 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,470 mm (57.9 in) wheelbase engineered for balanced agility and highway composure. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 130 km/h (81 mph).
