The first Harley-Davidson V-Twin engine was released in 1909 in the form of the Atmospheric V-Twin. Since that time the Motor Company has sold a total eight V-Twin engine designs – Atmospheric V-Twin, F-Head, Flathead, Knucklehead, Panhead, Shovelhead, Evolution, and Twin Cam – most of these names are instantly recognizable to almost any motorcyclist. So, when considering the relative rarity of Harley engine redesigns and the importance of the engine to one of the world’s biggest motorcycle manufacturers, you can bet that any major changes are well thought out and refined to a degree that lesser OEMs might have a tough time matching. With all that’s literally riding on a new engine, Harley’s project planners turned to the tools that have worked the best in recent years.
Harley’s Project Rushmore, unveiled only three model years ago in 2014, turned to members of the riding public to quantify what they wanted in a touring motorcycle. For the 2017 touring models, Harley’s researchers and engineers again picked the brains of both current Harley touring bike owners and riders who are interested in the marque but haven’t yet pulled the trigger. The result is the new Milwaukee-Eight engine. With interviews conducted in seven cities around the world, 1,000 riders were asked to outline what they would like to see in the next generation of H-D touring bikes.
