How often should motorcycle spark plugs be replaced

Motorcycle spark plugs are replaced every 30,000 kilometers. Most motorcycle spark plugs are installed on the right side of the engine cylinder head, but a few are installed on the left side of the engine cylinder head. The spark plug is commonly known as the burner. Its function is to discharge the pulsed high-voltage electricity sent from the high-voltage wire (burner wire), breakdown the air between the two electrodes of the spark plug, and generate an electric spark to ignite the mixed gas in the cylinder. A motorcycle is a two-wheeled or three-wheeled vehicle driven by a gasoline engine, with the front wheel steering controlled by a handlebar. It is light, flexible, and travels quickly. It is widely used for patrols, passenger and cargo transportation, etc., and is also used as a sports equipment. Generally speaking, motorcycles are divided into street bikes, road racing motorcycles, off-road motorcycles, cruisers, station wagons, etc.
