They are the same as with any other motorcycle, no different. The motor is hardly archaic, maintenance is the same as other motorcycles and only expensive if you go to a Harley dealer. Even then it's often not that much more. Harley's are very easy to work on, easier than just about any other motorcycle in it's class, as well as outside it's class. 99% of people who complain about Harley's, Have gotten their engineering degrees, from a cracker jack box. They know only what others have said, or what they made up. They don't like Harley's, or cruiser type of bikes. They have an obsession, with the latest, greatest, fastest, new thing. Doesn't really matter, they just need to put down, what they don't like. It's the in thing, not to like Harley's.
