1911 Harley-Davidson 7D Twin
The 1911 Harley-Davidson 7D Twin was one of the first bikes to be designed as a V-Twin model. Interestingly, this bike was released to the public as far back as 1908 and to this day is considered as one of the most historic and unique models. However, only four of these models were created, which has made the 1911 Harley-Davidson 7d one of the most scarce on this list. If you manage to locate one of those rides, it may cost you roughly $283,400 to own it. The Harley-Davidson brand is quite proud of its accomplishment in being a standout machine in the industry.
