Genuine carbon fibre replacement for the standard item - take off the old one, bolt this one on.
To answer the questions asked:
This was purchased from Duc Shop Tirol - I bought through eBay http://stores.ebay.c..._sid=1005828002
Very good service (delivered inside a week).
As for fitting, my dealer fitted all three items I bought together (rear brake master cylinder cover, headlight cover, and sprocket cover) in less than an hour and said it was easy.
