Built around Shineray's sport motorcycle platform, the 2023 Shineray XY400-390K features a 397.2 cc (24.2 cu in) oil & air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 27.1 HP (19.8 kW) at 6,500 rpm while maximum torque reaches 30 Nm (22.1 lb-ft) at 5,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 68.2 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.
Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,425 mm (56.1 in) wheelbase engineered for balanced agility and highway composure. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
