Yeah, post #4 is talking about a Y50. No way a Y50 is the right battery for a wethead.

I'm seeing BMW part 61 21 8 531 121 for the R1200RTW, same as the Yuasa YTX16-BS.
 
When I do a cross-reference for replacement parts, I-
Run the OEM number
Run the replacement number
“Sometimes” run a generic replacement query
All of these number need to match before I make the part purchase.

My Dodge with the 6-B Cummins came with a MOPAR filter with a part number that is different than the (WIX) application number. Number cross references seem to need to be validated.
