"Self-start" and "electric-start" are essentially the same when referring to motorcycles. Both terms describe a feature that allows the motorcycle's engine to be started using an electric motor, typically operated by a push-button or switch. This is in contrast to kick-starting, which involves manually using a kick-starter lever to start the engine.
In motorcycles equipped with self-start or electric-start systems, the rider simply needs to turn on the ignition, engage the clutch (in some models), and press the electric start button to initiate the starting sequence. The electric motor then cranks the engine, starting it without the need for manual effort.
The terms "self-start" and "electric-start" are often used interchangeably, and both refer to the convenience of using an electric motor to initiate the motorcycle's engine instead of relying on physical force or manual kick-starting.
