The real issues are how your bike is modified, how you ride it, and how often you service it. With few modifications, gentle riding, and regular servicing, it should last at LEAST 100,000 miles without any major work. I tend to do all three – ride reasonably (no burn outs, have reasonable starts, and have gentle stops), have only had a Stage I upgrade and exhaust work modifications on my ’13 Ultra, and have the bike professionally serviced with a prepaid service plan. So far I’m at 27,000 miles with no issues except routine maintenance. Brakes were replaced for the first time at 20,000 miles and the front tire replaced for the first time just this week at 27,000 miles. I rode my last Ultra 69,000 miles in three years under the same care with no issues, until it was hit by a car and totaled. My current 2013 Ultra I purchased in late 2015 with 2,000 miles on it, and put another 25,000 miles on it 15 months. The again, I drive and maintain my car the same way, and put 104,000 miles on my 2002 Mercedes 240 C before I had to even change the tires. Brakes were changed at 160,000 miles for the first time, along with the transmission fluid. So the bottom line is if you take care of the bike, it takes care of you. I have no qualms with jumping on my bike and spontaneously riding 1,500 miles on a weekend and have done it several times. I know many people in this forum look down on professional maintenance, but as a surgeon I don’t have the time to work on the bike. I also commute very day on my bike, even in winter. I’d rather be riding it long distances when I have time off instead of working on it, and have ridden through about half the states on two wheels. As a person who rides about 24-25k miles/year, with a one-time fee lifetime maintenance plan, the shop loses a LOT of money on me with my tune-ups. I think they truly hate me at this point. On the other hand, I have friends with Hogs who regularly do burn outs, take every turn like the devil himself is after them, come to screeching halts every other stop, and have modified their engines so heavily that the torque and horsepower are bumped by at least 30%. Their bikes spend a LOT of time in the shop with expensive modifications and rebuilds. I prefer to treat the bike nicely so I can ride as long and as far as I want without worrying about breakdowns or rebuilds. I think you will have the same experience. I hope that answers your question.
