At the heart of the 2011 Xingyue XY400GY sport motorcycle, Xingyue relies on a 387 cc (23.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 29.5 HP (21.5 kW) at 7,000 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 76.2 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the XY400GY measures 161 kg (355 lbs) dry, translating to a power-to-weight ratio of 0.18 HP/kg (5.46 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,455 mm (57.3 in) wheelbase engineered for balanced agility and highway composure. The 22-liter (5.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
