Speedometer won't work - Kymco 2013 UXV 500 IRS 4x4

Question edited for clarity.
Question moved to model category, 2021 or 2012 though?

Likely to be the vehicle speed sensor (VSS). Check the connections on it.

The speedometer on a 2013 Suzuki KingQuad 400 ASi is connected to the speed sensor, which is mounted on the transmission. The speed sensor generates an electrical signal that is sent to the vehicle's Engine Control Module (ECM). The ECM then uses the signal to calculate the speed and sends it to the speedometer for display on the instrument cluster.
If the speedometer is not functioning, there may be an issue with the speed sensor or the wiring between the speed sensor and the speedometer.

Not sure why but Honda in their infinite wisdom integrated the 4WD among other functions into the speedometer on a few years. If your speedometer doesn't work either chances are you need a new speedometer. At like $400! It is what happened to mine. If you start run the engine at all with a dead battery (hand start, jump etc.) it WILL fry the speedo, the 4WD the reverse bypass, etc. I learned the hard way.

If you have the front wheel off recently one, the speedometer sensor is easily broken and a common occurrence when the wheel is removed and replaced.
The symptoms are erratic or non-working speedo.
Also, there is a wiring harness under the speedometer. Remove the 3 bolts holding on the speedometer, and carefully lift it up and check to make sure the harness is plugged together tightly.

It needs to be calibrated, you can't do that at home.

Check to see if the speedometer cable has vibrated loose at the speedometer back. I have seen that a few times.

check to see if voltage is coming off the stator while running, AC volatage, from all 3 wires. if thats good you prob need a regulator/rectifier.

Look at your Magneto Flywheel , sounds it jammed .
