You may use the one provided by BMW (headquarter). This one already contains the 2012 S-RR. However, you will have to pass a couple of web pages in German language first. Here's how to proceed:
- Go to BMW Motorrad Deutschland
- Choose "Services" within the top navigation. In the middle column (with the headline "Service und Technik" click on "Elektronischer Teilekatalog"
- On the right side of the page opening now, klick on "WebETK" (just below the large picture on top).
- Enter the code shown in the box and klick "Absenden". Please note that the code is case sensitive! That's the last step in German.
- Now you're within the parts catalogue and can either browse through the models or enter the VIN of your bike on the top.
All other things should be self-explaining
