From Monte: << I don't know if the stickers were OEM purchases or a sourced replacement. >>
There's another thread from a few months back on this topic. I recall someone posting a recollection that the decals came with the bikes, but were not affixed to the battery covers at the factory. Perhaps they were sometimes applied by dealers, sometimes by the new owners, sometimes not at all.
The BMW part number for stickers for dual-shock R65s gets the purchaser a white sticker with no shadow. (I had to go to the garage and check those on my '81 to be certain.)
