There are several things that can cause your speedometer to stop working. The most common cause is a blown fuse. The second most common cause is a malfunctioning speedometer cable.

why would a speedometer and odometer not work on a suzuki motorcycle?
If the speedometer and odometer are both not working, I would blame the speed sensor. If only the speedometer does not work and the odometer does work, the cluster is bad.
Why doesnt your speedometer work on a 02 Mits Galant
Your speedometer might not be connected if it does not work. It might also have blown a fuse if it is an electronic speedometer or it could have a wire that is loose.
The speedometer sensor is probably bad.
The gears in the speedometer are stripped. If the odometer is working then you have input.
