Oil filter alternatives
Didn't want to use the BMW filter, so I set out to find a readily available automotive oil filter. I choose a Royal Purple 10-2876 because it has a thicker shell and synthetic filter media, I have used the 10-2835 on my 2015 R1200R for 12k+ miles with excellent results. Other filters that fit are the Bosch 3300 and K&N HP-1008, others cross over as well. All of these also have an anti drain back valve as well, not mandatory but definitely an improvement over the stock filter. They have about twice the filter media and oil capacity over the stock filter. The belly pan did fit unmodified but did barely touch the filter, I removed a couple mm's with a file to make it clear, took a couple minutes.
