Hi all!
I pick up my 2013 Super Glide Custom very soon and have a question regarding the speedometer.
My bike is an European import so currently has a speedo that reads only in KPH with a stickered overlay to show MPH.

I can deal with the overlay short term but would like something a little cleaner.

I've been looking at something such as this:

Looks like a good option and I believe locks to the bikes ECU after 30ish miles.

However I've been offered a UK speedo at a good price (shows both MPH and KPH) from a bike that was removed straight after delivery (so only has 10 miles on the odometer).

So my question is this, would the UK speedo I've been offered be locked to the bike it was taken from or would it have the 30 miles before locking like the speedo I linked to above?
And also would the odometer automatically convert to total miles from total kilometers?
