How often should spark plugs be replaced in a new motorcycle?

[AngelaRose]

New motorcycles should have their spark plugs replaced approximately every 20,000 kilometers. Spark plugs are critical components of the engine, and their performance directly affects the engine's functionality. The roles of spark plugs are: 1. To introduce the high-voltage electricity generated by the ignition coil into the engine cylinder; 2. To generate sparks between the electrodes of the spark plug to ignite the air-fuel mixture, ensuring the engine operates normally. Motorcycles are vehicles driven by gasoline engines, with two or three wheels steered by handlebars. They are lightweight, flexible, and fast, widely used for patrol, passenger and cargo transport, and also serve as sports equipment. Motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes, among others.
