Hi, and welcome. Very interesting that you have Rothmans kit. Have been looking at the same for my 2004! https://shop.auctmarts.com/fairings/honda/cbr1000rr/2004-2005/1d5.html Great bike. Hope you have many happy miles!!
Can't take any credit for it, but does look good. Certain it isn't the original fairing but looking forward to getting out on it in the new year.
