Fork seal issues. One of our forum members, Elcanaco, and I rode to the Arctic Circle via the northern Yukon in 2015. His fork seals both went, drenching his front brakes with oil and he rode about 2000 miles to his home in Castlegar BC with only a rear brake. Upon ordering new ones he learned that there were problems with the seals..I believe there was also a recall for the tappets. I can't recall what year his is. I'm going to send him a note to take a look at this thread
The front bearings went out on my DL650, also on the ride home and I learned that they were an issue.
