The starter relay in a motorcycle is an electrical component that acts as a switch to engage the starter motor. When the rider presses the starter button, the relay receives a signal and activates, allowing high-current electricity to flow from the battery to the starter motor. This action cranks the engine and initiates the starting process. The starter relay helps protect the starter button and other electrical components by handling the high current required to start the engine and ensures reliable engine ignition.
