I have a 2003 R1200 CL. My parts supplier suggests Bel-Ray petroleum 20-50 oil with no explanation, but my shop mechanic at a BMW dealership suggested BMW Advantec 15-50 oil due to its better lubricating values (his opinion). I have a Clymer manual that also suggest BMW Advantec 15-50 oil. My reasoning is if an oil matches the manufactures Api, Jaso, etc. required numbers it should be ok. Although I'm leaning towards the BMW Advantec oil because that's been ran in this motorcycle from previous owners and that's what I try to run in it.
