Thruxton Swap Instrument Panel On Thruxton 1200

I have a similar question in terms of gaining a rev counter on a Street Twin with the connection and loom being so similar to others.

Assuming we are talking analogue here..... back in the good old days for your issue, companies supplied Kmh stickers to simply place over the clock glass.
It can't be that hard on Autocad etc to create your own sticker with the right dimensions and demarcations to suit.
For you, personally, I wouldn't change the clocks.

 

you can switch modes between MPH and KMP

 

Very easy, just buy the EU internal panels (they are thin plastic circles), open the clocks and replace it. Bit of a hassle but I am not e great mechanic and I did it several times.

 

Well, I installed the Artons, like them. I looked it up, I don't think Triumph sells the panels separately, only the complete kit, a bit expensive I guess. Maybe look for second hand?
