Positioned in Xingyue's atv motorcycle lineup, the 2011 Xingyue XYST400 features a 400 cc (24.4 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 26.8 HP (19.6 kW) at 6,500 rpm while maximum torque reaches 32 Nm (23.6 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 67 HP per liter and a 1,000 rpm working window between peak torque (5,500 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 XYST400 measures 275 kg (606 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.26 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,250 mm (49.2 in) wheelbase engineered for quick, flickable steering geometry.
