What is a motorcycle spark plug used for?

As the first component involved in combustion in a gasoline engine, the spark plug plays an essential role since it is responsible for igniting the air/fuel mixture in the engine’s combustion chamber. This combustion generates the power needed to move the vehicle.

To ensure optimal combustion, the spark must occur when the piston reaches its highest compression point. The quality of this ignition influences many factors affecting riding and the environment, such as performance, engine efficiency, and reduced emissions.
