Rob Valdez was posting about the owners manual part number, and one version still available from BMW .
I think there were three versions originally available, one for the '78 -'80 model year bikes, sometimes referred to as the first generation R65, then the '81-84 years including the LS version, referred to as the second generation, then the '85 and later bikes , known as the 'monoshock' bikes .
I believe that chapter 01 in the BMW parts catalogs, is the section for literature, and its not listed for all bikes .
