Slow speedo.

My speedo reads slow ( shows 60 when doing 80) not too bad at low speeds. Has anyone any ideas please. Ahab .

The speedo on my le mans did the same so I ended up changing the speedo and all is good now. :smiley:

What bike is it Ahab? there are several gearing options at both the speedo and gearbox end.

Mine stopped going much past 50 even at 100 mph, so ditto. Plus it was in km
