Typically, motorcycles have a charging system that is designed to replenish the battery while the engine is running. This means that you can charge the battery while riding, and it won't drain power from the engine or make it harder to keep moving forward.
The charging system in a motorcycle usually consists of a stator, a rectifier/regulator, and a battery. The stator is connected to the engine and generates electricity as the engine runs. The electricity produced by the stator is then converted into direct current (DC) by the rectifier/regulator, which charges the battery.
While you're riding, the engine powers the stator, which in turn charges the battery. The charging system is designed to provide enough power to run the motorcycle's electrical components, such as lights, ignition system, and other accessories, while simultaneously charging the battery.
In such cases, you might experience electrical issues or even a complete loss of power.
It's always a good idea to periodically check the battery's condition and ensure that the charging system is functioning properly. Regular maintenance and inspections can help prevent any potential problems and ensure that your motorcycle's battery stays charged while you ride.
