On the last day of my 3 day trip to Nevada the speedometer on my 2002 SV650 stopped working. It actually worked intermittently, showing speeds of 40-50mph. A quick Google search showed that the speedo magnet could fail.
Here is the broken one (12 years, 22k miles of usage) next to a new OEM (part number 34983-21E00) I picked up from the local dealer
It was a real easy swap, 15 minutes tops. The big challenge was to mount back the front wheel alone using a combination of my hands and feet. I managed it somehow 🙂 The front stand definitely helped.
