Harley Davidson motorcycleIf you're a biker and you really love motorcycles, then you need to know something of the storied history of the most famous motorcycle brand in the world: the Harley Davidson motorcycle. Did you know that the first Harley Davidson motorcycle was sold in 1903? That first Harley Davidson motorcycle was intended to be a racing bike with a 3-1/8 inch bore and a 3-1/2 inch stroke. The first H-D factory was extremely modest: it was a 10x15 wooden shed with the words "Harley-Davidson Motor Company" scrawled on the door. A young school friend of Harley and Davidson bought one of the 1903 models from the founders. If it still existed, this early Harley Davidson motorcycle would be a priceless collector's item.
