Sorry, but as you can already tell, you are not going to get a concensus, unanimous answer on this one. Glider referred to the method you will find discussed in great detail under the Quick Tips link at the top of the page. I read this entire article and it made a lot of sense to me but I can't find anyone else 100% recommending this method.
Hobbit refers to what I would say is the majority opinion - ride at a wide variety of RPM's without overdoing it at the low or high end.
As I prepared to ride away on my new 08 Street Glide, all the salesman said to me was, "take it easy the first couple hundred miles." What, exactly, is that supposed to mean?
I'm not a mechanic by any means but it seems to me like no matter what method you choose, the most important thing is to change the oil/filter early and often during the break in. It only makes sense that this is when the metal parts are rubbing and wearing the most and the oil is filling with the residue of that process.
As many others have said, just my two cents worth!!
