Something you do not see everyday

(DISCLAIMER... I do not know if the kph speedo is based on the same speedometer configurations as mph speedos)

But Yep it should be as simple as a speedo gear change. And there is nothing on the speedo to indicate mph or kph.

Assuming my math is right. IF your current gear is 32 you would need to slow it down so you would need a 51 tooth give or take.

32 teeth x 1.609344 = 51.5 teeth

There might be some limitations to the gear teeth. There are adapters that are variable that can convert, might even be a dedicated converter.

Mph x 1.609344 = kilometers per hour
60mph x 1.609344 = 96.56kph
