A Harley Takes an Engine From Porsche. NO wonder many riders don't know what to make of the new V-Rod from Harley-Davidson: The engine was designed in Germany by Porsche and it has the first water-cooled engine in Harley-Davidson's 99-year history. The V-Rod doesn't look like any other Harley.
It proved to be extremely popular until the overhead valve engines arrived and was the first V-8 readily available to the masses, but it was not the first. LÃ©on Levavasseur took out the first patent for a V-8 gasoline engine in 1902. Although not a production engine, it was utilized in several aircraft and competition speedboats of the day.
