- honda moly 60 spline lube
One that seems to hold a good deal of favor is the Honda Moly 60. I have personally used Dupont Krytox hi temp (and hi $) due to some compelling test results.
There are probably several others but both of these are readily available
and should keep your splines in fine shape.

I use BMW #10 grease and do a spline lube everytime I put on new tires. This results in an every 10000 miles or so lube job on the average.
Many recommend using a molybdeum grease, like Honda Moly 60 to do the splines. This is probably a better grease for this purpose than the BMW #10, but I am of the opinion that the frequency of doing the lube is more important than the grease used. If you plan on going longer intervals between lubes ( 20,000 miles or more) the quality of the grease takes on an added importance.
I bought my current "88 K100LT with about 40,000 miles on it. It had been used to pull a trailer. The splines were shot when I checked them at 50,000 miles. I don't know if the problem was inadequate lubrication, or the use of a trailer. I ended up buying a low mileage driveshaft, swingarm, and rear end off a wrecked bike for around $250. I have used BMW #10 since then with no visible degradation of the splines.
This topic should generate several differing opinions about spline lubrication.

Great stuff. If he decides to ever write a K-bike book, I'll be first in line to buy it...

Thanks for all the great info. I was able to get the BMW #10 at the dealer in London ON and even remembered to pick up a spare clutch cable. Should be good for a while. My 93 K75S has only 32,000 miles on it so far and my intention is to wear it out. From the looks of things it mat last longer than I will...
Thanks again

See if you can return the #10 - it is NOT a good lubricant, and whatever the dealer had was "old stock" - BMW recalled it all about 5-6 year ago. Then go to the Honda dealer and get the Honda Moly60.
#10 was a mistake by BMW-NA - one they bought a lot of and being BMW - they didn't want to admit that it was a mistake. In hot weather it turns to a liquid and will disappear off your splines. It also contains no extreme pressure component at all - making it a very poor choice for this application.
Or not - it's your bike..

If you ride 10K a year your will need about 30 years to wear it out. By then it will be a collector's item and you can sell it for enough to buy a new bike.

Honda Moly 60 is OK, but 60% moly is drier than desirable and has less anti-corrosive characteristics than I personally like. I mix it 50-50 with Wurth 3000 sticky green grease and the results are outstanding.
Sources of good moly paste products similar to the Honda paste ar www.tsmoly.com and www.guarddogmoly.com.

spline lube
After much research, I use Loctite 51049 Moly Paste. It is 65% moly and supposedly good up to 750 degrees F. I got it from smallparts.com. Like most Loctite products grossly overpriced at $25.00 for an 8 ounce can. It has great stickiness.

Spline lube suggestions
I did a rear main oil seal and clutch replacement on my 97 K12RS this winter and, in the process of reassembly, lubed transmission output shaft & final drive splines w/ never-seize BMW part # 83239407830.
For the transmission input shaft & clutch I lubed the sliding surfaces w/ Castrol Optimol Paste TA, BMW part # 18219062599.

Spline lube
When I was at the factory service school our instructor recommended the Wurth SIG3000 over the BMW #10 and the old staaburag that BMW used to use. Been using it for years with no evident wear.
Cleaning and re-lubing with every tire change is a good interval. Also use it on clutch splines.

NO! The M-B sunroof paste has no moly/extreme pressure qualities... you'd be better off using generic C/V joint grease than the sunroof paste, for sure!
The reason I ask is because of threads like this one mentioning krytox as being a flourinated and superior alternative to molybdenum grease. https://advrider.com/f/threads/final-drive-spline-lube.66868/
https://www.euromotoelectrics.com/product-p/lube477.htm
This is a good choice, click on the technical specs tab to read the moly content. Not cheap, but if you do it yourself it's cheap considering a dealer would charge $200.00 for the job. Chunk.

I only read part of this thread but some of the opinions are nonsense. I don't know about flourinated krytox but molybdenum disulfide (moly) is a well proven spline lubricant for splines.
