Service Bulletin but not for the RS?

[Pyrrho]

Despite this valve I’m still having my drive shaft pulled on the RT and lubed at the 12,000 mile service just to be sure it is lubed properly.

The latest Revzilla DailyRider video that was released I think this past weekend had Zack riding a R1250RTP. A viewer question near the end of the video asked about maintenance, so Zack said he asked a BMW rep that worked with all the CA police departments and their RT fleets, and the only thing he would concede is drive line issues. U-joints specifically, didn't mention splines. U-joints will fail no matter how well lubed starting around 80K on the RTs (yes I know your uncle's brother-in-law's neighbor is still riding a RT with 500K and an all-original driveline, he's not typical).
