The speedo assembly, also known as the speedometer assembly, is the complete unit responsible for measuring and displaying the motorcycle's speed. It typically includes the speedometer gauge, which indicates the current speed, and may also encompass additional components such as the speedo drive, mounting brackets, and wiring or cables. The assembly converts rotational motion from the front wheel or transmission into a readable speed display. It is mounted on the motorcycle’s handlebars or dashboard, providing the rider with essential speed information for safe and efficient riding.
