For a collector’s item, this 1922 Harley-Davidson JD is about as rare as they come in this condition. However, it wasn’t rebuilt just to collect dust in a museum, it starts up immediately and can cruise to 60 or 70 mph just like it did in 1922. It reflects the long, storied history of what might be the most popular motorcycle brand in America. Its rider will bring a one-of-a-kind motorcycle wherever he or she chooses to go, and that is the allure that will be sold this month at the St. John’s auction.
