Harley Twin Cam vs Indian Thunderstroke vs Honda Gold Wing Which Engine Actually LASTS

I put Harley’s 1450cc Twin Cam 88, Indian’s 1811cc Thunderstroke, and Honda’s 1832cc Gold Wing flat-six against the question that matters after the showroom shine fades: which engine actually lasts? I trace the quiet nylon wear inside Harley’s cam chest, the modern design choices behind Indian’s V-twin, and the rubber component Honda never scheduled for replacement. I also compare smoothness, long-term durability, failure modes, and what happens when each engine finally stops making power, because mechanical longevity is not just about mileage. It comes in two very different forms. 0:00 The real durability ranking 2:56 Harley's cam-chest time bomb 6:13 Indian's modern V-twin design 8:57 How long Thunder Stroke lasts 11:07 Honda's smoothness advantage 15:14 What happens when engines die 17:40 Two kinds of mechanical immortality
