As a 2012 (Mark I) owner, I will add that just last week I turned over the 10,000 mile mark.
1 - Aside from a bum Cycle Electric alternator/rectifier zero engine problems. Harley-Davidson unit has performed flawlessly!
2 - Original compensator still works. No problems except when lugging. Don't lug.
3 - 'Comfort kit' added. Vast improvement! Hate the name and the up-charge for the privilege. This was worthy of a recall if anything was.
4 - Rear sprocket and belt replaced due to excessive wear and noise. Already lined up for the second replacement under warranty. In this I feel like a Beta tester.
As you can see from the miles, I have not let this slow me down in enjoying the car. Yesterday was a phenomenally glorious day in Vermont and we put on over 200 miles on these beautiful curvy mountain roads with stops at the various brew pubs...
No matter what, I feel I received my money's worth! This car has been a hoot to drive!
