Question about 1989 BMW K 75 S
Your K-bike service manual and my own K-bike experience suggests changing the final drive oil once a year and lubricating the splines about every 30k miles. On my '85 K100 I went 130,000+ miles with only one final drive issue, a seal failed in the final drive.

Hi and welcome to FixYa,
Offhand, re-lubrication would depend on how often the bike is used as well as distance traveled. Normal usage would require at least once a year. Of course when greasing the driveshaft, might as well change/fill differential oil. Not really that difficult, other than the 8 bolts on the differential, the challenge is fitting back in the driveshaft to the gearbox output spline.
Good luck and Thank you for using FixYa.
