I've got a 2016 Urban Enduro. Just hit 5,100 miles. It has been slowly gathering more and more oil around the lines below the belt cover for some time, mostly it was just a fil of oil and took about 500 miles to build up, but on a recent trip it got bad enough to mist on my foot on the highway. I had read quite a few bikes had an excess amount of assembly grease in the belt cover and over time with heat it melts and leaks out. I really dont believe that's whats going on here. I'll be taking it back to the dealer in about a week and a half and will post an update then with what they have to say. If anyone has had a similar issue please post up your experience. I will post some photos asap.
