Hi all,

I have a 2013 Vespa PX125. The speedo works perfectly fine, however the odometer is stuck on 7000km. I assume this isn't a speedo cable problem as the speedo is working.

Any ideas on what it could be?

Thanks

Whatever gearing in the speedo that rolls the odometer is probably broken/ worn. Built like a clock with springs and gears. Everything is sealed so there's no chance you can get in there and poke around.

Here in the states, theres an old timer that repairs speedometers for fun. You may have someone over there that does that? Like most things though, its probably cheaper to replace the whole thing than have it repaired.

I just sold a Lambretta LI125 series 3 last year that had the opposite problem, the speedometer stopped working but the odometer never stopped working. Speedoking is a reputable company for repairs.

You can always hook up the cable to a drill and start running it with the speedometer out of the scooter and see if you can spot something. It is worth looking at.

You can get the replacement glass and bezel sets. If you are brave you could take the bezel off and then take it apart from there. As said, there are springs, cogs etc so take care and remember where things go.

and, move the speedo needle back past its stop so you can see its untensioned/resting position before you take it off.
