For what its worth, I used Bike Fairings AU for a Rothmans set for my 28SP.
As Charles said, fit pretty good, bit of cleaning around the holes, paint quality very good considering the price. very good for the money. One panel had been cracked, poss caused through transportation or packing, they sent a replacement instantly. Outstanding service.
You do have to take the odd chance, as I did, and for me it was a success. I'd certainly use them again.
Eggsy.
