Built around Xingyue's minibike, sport motorcycle platform, the 2011 Xingyue XYQH-815B relies on a 50 cc (3.1 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 3.4 HP (2.4 kW) at 8,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 68 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
Rider ergonomics and chassis geometry center around a 580 mm (22.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 970 mm (38.2 in) wheelbase engineered for quick, flickable steering geometry. The 1.8-liter (0.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 55 km/h (34 mph).
