MT-125 Speedometer showing kmph number for mph, faulty speedometer

[JamieRider]

I bought my 2014 MT125 1 year ago, but didn’t ride it until months after it’s warrenty from the seller so I can’t bring it back to them. Now I’m riding more and doing DAS soon, so I want to sell it eventually for a bigger bike after DAS but need to get this sorted first.

Currently the speedometer is in mph but at

- 20mph, it shows around 32

- 30mph, it shows around 50

- 40mph, it shows around 65

etc 

This leads me to believe that it’s showing kmph speeds. I have changed the dash to show kmph but that makes the numbers even higher and completely wrong. 

Any clue on getting this fixed?

Has the previous owner changed the sprockets? A lot of smaller engined bikes are over geared and people change the sprockets to make more usable ratios. This can throw the speedo out.

I don’t know. Is there any way to check if it’s the sprockets? Though, from what I know changing the sprockets would probably throw the speedo out a bit but not change it to meaure in kmph completely.
