I let people use the arguments on me of Harleys are too high, they don't perform well, they aren't reliable, etc., but the simple fact is buying a motorcycle is not a rational act, it's an act of passion. If you want a Harley, get what you want as long as you can afford it. Oh, and take the riding class.
I bought a Harley simply because of the sound. They have a patent on it and I can tell a rice cruiser a mile away. About the only motor that sounds similar is an S and S V-twin. I also have a Cessna 195 with a radial engine that is often said to sound "like a pack of Harleys"....something about that "potato patato potato" produced by that master/articulating rod layout that I never tire of hearing....
