If Harley-Davidson needs engineering consultancy there is its long relationship with Porsche. At the moment Polaris with its Indian brand is constructing value from the domination of American Flat Track and some see this partially as a result of the purchase of Swissauto. Yet the H-D product most closely tied to the Porsche relationship, the V-Rod, has only a fraction of the popularity of the Motor Company's traditional Big Twins. The Big Twin's time-honored features of rolling bearings, air cooling, knife-and-fork connecting-rods, and multi-piece crankshaft are not something with which Harley needs or wants engineering help. Like the old timers used to say, "Runnin' good? Don't touch nothin'."
