I'm hoping to get some advice relative to a diagnosis of a final drive failure relating to the crown bearing failure and grooved axel.
I have had this 2009 K1300GT for about 2.5 years. I purchased it used with about 13,000 miles on it and have put about 10,000 miles since. I had the annual service performed at the dealer this spring which included final drive fluid change with no feedback from them regarding any concerns about the final drive.
The last few rides I had taken, I occasionally felt a brief odd vibration sort of like a patch of rough pavement. It wasn't repeatable and was very subtle so I didn't think it would be fruitful to have looked at.
This past weekend while at highway speed I again felt the vibration but a bit stronger. When I could stop and check on it, there was a lot of grease slung onto the disk brake and rim from the center hub. To avoid doing any further damage, I stopped riding it and took it in to the dealer to be checked out. Having done a bit of research, I was hoping it was just the main bearing and perhaps some seals ($500???).
The estimate from the dealer is for a complete final drive for a bit less than $2,000 plus an hour of labor to install.
So.....where do I go from here? I love the motorcycle and being 6'7" there aren't a lot of bikes that fit me.
I am thinking about calling BMW customer service to see if they will do something for a 5 year old bike that is in otherwise great condition that has only made it 2/3 of the way through the original 36,000 mile warrantee distance (but 2 years beyond the 3 year warrantee).
It seems prior years/designs of the final drive were notorious for failure but it seems to be better the the more recent bikes. Might it make sense to find a used final drive from a k1300gt or K1300s that was low milage and perhaps totaled due to front end damage? If used is viable, what price would be reasonable?
