What does motorcycle chain engine mean?

[WestonAnn]

Motorcycle chain engine refers to the linking mode between the engine's internal valves and the crankshaft. Advantages of chain engine: The main advantages of chain engines lie in their smooth operation with minimal vibration, smooth acceleration, and high top speed, whereas pushrod engines excel in strong explosive power, simple structure, and easy maintenance. However, their significant drawback is excessive vibration, which reduces user experience and riding comfort. The widespread adoption of chain engines is primarily due to their stable performance and low vibration, making them the preferred choice for vehicles ridden on plains. Chain engine motorcycles: In these motorcycles, the crankshaft drives the camshaft via a timing chain, which then operates the valves to open and close at the right time, with the camshaft positioned overhead. In contrast, pushrod engines use gears and pushrods to drive the camshaft and valve rocker arms, with the camshaft positioned lower. Comparatively, chain engines produce less noise and vibration, offer better acceleration, and are more suitable for high-performance, high-speed, and large-displacement models.
