Does your speedo still work? What year classic is it as earlier ones were on a mechanical drive and if yours has the km/mph convertor that could of failed. The later classics have an electric fed sensor.

Now I think the speed sensor is in the clocks and it may have failed, you could try a ecu reset to see if it still does it.

May need to check the speedo cable or converter

Have you checked the converter is plugged in/working properly?

There is a 'sensor' of sorts (on a import), it's detecting the rotations from the speedo cable (& stops people 'easily' removing the 112mph limit) & sends a pulse to the ecu ...iirc it sits within the speedo just above the milometer ...you'd have to remove the clock & then it's face to see it ...& looks like two very fine contacts. Id hazard a guess that it's this that's failed/failing & it's new clocks time.

Oh & as a 'temporary' fix (because the limp mode can be bloody annoying!) you can run in diagnotic mode ...although i wouldn't advise doing this for long
