Yami,
The short answer is yes its possible as fairing weigh next to nothing but they take up the space but if I have room, I'm happy enough to bring some back but… I'm not sure I will be going again for some months as the biking season is nearly over…
I'm happy enough to send my contact details if you want them?
Hello Michael,
I have brought a few bikes from UK and put Swedish plates on them and its easy enough but it does take some time and its all explained

Regarding the headlight price, you start looking for one on here, blocket, UK ebay etc and the cheapest way is to change them yourself or with a mate.
Most modern bikes have digital speedo’s and they can be changed by pressing a few buttons and its easy enough as Google will find how for you in a few mins.
