I would be want to know for sure that the dash for a '05 12 isnt "hardwired" into the electrics of the bike first Seraph.
I am not saying I know anything about it yet (although I am fightering my old 12) but I
think you will find the bike doesnt run without the (original) dash being wired up. I am sure you can find a way around it but just check it first
I am going to get a Veypor for the 7 which is also naked. Something to do with smashing them I guess.
