Back in the 1930s Orly Courtney designed a motorcycle called the Henderson Streamline. The bike was designed with aerodynamics in mind and gave out 40 horsepower with the ability to reach a speed of 160 kilometers per hour.
The streamlined Henderson was a pure concept vehicle, built to express modern concepts and Courtney's artistic vision. The conservative motorcycle community of the era did not understand it. References to it in print often used the term Buck Rogers, treating it like something out of a futuristic cartoon.
In truth, that advanced design did bring with it some real-world problems. While beautiful, the machine would not have offered a very comfortable ride for the road-going motorcyclist Courtney said was his target. The seating position is cramped, especially for a tall person.
