Every year Interbrand releases a list of the Top 100 global brands — ranking each company on its brand value and then assigning a dollar amount to that value. As such over the years, the Interbrand 100 has become the de facto metric on the strength of a company’s brand. For some time Harley-Davidson has been a stalwart of the Interbrand 100, with the Bar & Shield brand regularly getting the nod from the consultancy’s specialists — after all, how many brands are responsible for enthusiasts tattooing its logo on their body? However the past few years have seen a worrisome trend, as slowly Harley-Davidson has fallen farther and farther down the Interbrand 100 rankings.
