Fork upper lower fork pivot joint boots cracked

I recently had some brake work done on my 2001 KRS. The technician pointed out to me that both upper and lower fork pivot ball joint boots are cracked (not sure what you call those joints). The concern is about water getting in there and compromising the steering. I rarely ride in the rain and my bike is in a garage when I am not riding it. I understand it is a very time consuming and expensive process to replace those suckers.

I do not notice any issues with the steering at this point.

My question is: How long should I continue to ride it before feeling unsafe or that I am screwing up the bike by not replacing the joints/boots?
Thanks

Re: Fork upper lower fork pivot joint boots cracked

I'm not sure I have an answer for you, but for what its worth, BMW issued a service bulletin on defective ball joints years ago, and while I doubt that it would be honored, you might inquire at the dealer to see if it's still applicable, here's the document,

These tend to eventually crack with age - mine are OK after 16 years, but your mileage will vary...

These 2 Ball-joints are greased for life, but with a cracked protected rubber, the wear might go downhill fast - dust and water gets in and grease gets out.

BMW has never sold this rubber parts separately. HOWEVER because it was fairly common problem on R1100/1150GS Boxers doing more off-road, there is an aftermarket solution. You can buy these from the nice folks at BeemerBoneyard for $20 each:
https://www.beemerboneyard.com/balljointboot.html

The link above will give you 4 links to YouTube videos about installation. Our K1200RS front telelever is sligthly different than the one on the videos, but you will get the idea if you want to tackle the replacement yourself.

Re: Fork upper lower fork pivot joint boots cracked

The Beemerboneyard boot fits the K12RS and is a great solution to the cracked boot issue. Keeping that ball joint clean, covered, and lubed it will last a long time.

Re: Fork upper lower fork pivot joint boots cracked

Wow thanks for this information! I have never had any issues with the low or high speed handling of the bike. Just want to make sure nothing snaps off :-)
