The Indians of those years were without doubt the best looking bikes made in the US of A. Years ago I had a 46 model. The attached pic is my 41 Knucklehead. In comparison the Indian has a lot more charactor. The Knuckle OHV was the Harley engine that ultimately spelled doom for the Indian flatheads. Built from 36 to 47 and then the simular Panheads thereafter were all OHV engines that were hard to beat with a flathead no matter how much better the bike looked.
