At what RPM should a 400cc motorcycle shift gears?

[McMaria]

On flat roads with minimal headwind and light or no load, a 400cc motorcycle can shift gears at 3000 to 3500 RPM; on moderate slopes, shifting should occur between 4000 to 5000 RPM; in conditions with strong headwinds, uphill climbs, or heavy loads, higher RPMs are required for gear shifts. In general, the shifting point should be determined by the smooth and consistent sound of the engine, and the shifting range needs to be adjusted based on the load. As long as the engine isn't lugging, shifting earlier will save more fuel. Motorcycles are gasoline-powered vehicles with two or three wheels, steered by handlebars to control the front wheel. They are lightweight, agile, and fast, widely used for patrols, passenger and cargo transport, and also as sports equipment. Broadly speaking, motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes, among others.
