What does a speed sensor do on a motorcycle?

A speed sensor measures the rotational speed of your transmission's output shaft and sends that information to your motorcycle's computer. This data is used for your speedometer, odometer, and can affect systems like cruise control and engine management.

Why would I need to replace my speed sensor?

You might need to replace your speed sensor if your speedometer is not working correctly, if you're experiencing intermittent speed readings, or if a diagnostic scan reveals a fault code related to the speed sensor circuit.

Does this speed sensor come with any mounting hardware?

This product listing is for the speed sensor itself. Mounting hardware, if required, is typically sold separately or may be reused from the original installation if it is in good condition.
