Absolutely sick bike, hands down.
I don't own one, but I would brace for the 1190 being brutal on oil. Shearing in particular.
First question is what your min riding temp is, then how long you want to go between changes.
Botique oils abound, and you can't go wrong with those. Motul, Bel-ray, Maxima, and Redline are some that come to mind. Even with these, my main doubts are that you could do the full interval, but that bit's conjecture until I see a UOA from someone with an 1190ADV-R. To that end, I'm sorry.
Ill try to answer your question from the lower-cost front. All of these I am confident will not compromise your bike's life:
Mobile 1 15w50 (PCMO-syn) is a good option (I'm curious how they formulate it as an SN though, lately, and whether its just as shear-stable as past blends)
Mystik 15w50 (HDEO-semisyn) should be a good option too if you want to reduce the OEM interval--same applies to above.
Valvoline synthetic or Mobile 1 (MC/4T) 10w40 with 20w50 (or just 20w50) would hold up. Some people report consumption on
other sites.
Rotella CK-4 T5 15w40 (HDEO-semisyn) combined appropriately with a 10w60 will work. the new CK-4 Rotella T5 looks to be amazingly shear-stable in its own right (Check recent UOA here.)
I am currently running a blend between T5 and Maxima Extra4 10w60 on my adv bike to get a durability and cost I wanted. That Extra4 is primarily an ester from what I was able to find, and it's also stuffed full of organometallics. "4T Compliant sweetener" is how I'd describe it. For what it's worth to you, the blend is smoother shifting than Castrol 4T racing full synthetic 10w50, which went in last.
Use this if you want to mix!
