The story of Harley Davidson is one of a motorcycle that came to be as American as apple pie. But it's not been an easy ride. This interesting video traces the incredible highs and plummeting lows of an American icon and points out the problems facing the company.

The Problems facing Harley Davidson and How They Can Solve Them

OK, so this video is a couple of years old but it is a fascinating recap of the story of Harley Davidson up to that point. I know things have changed again since then but it's interesting to put today's H-D into perspective with what was happening then.

At one point, Harley could do no wrong but then its customer base started ageing and prices kept on rising, keeping them out of the hands of younger buyers. The financial crash of 2008 didn't help matters.

But, Harley has survived and now, with a new CEO, Jochen Zeitz, at the helm, has belatedly started to look at its product line-up - once exclusively centred on its traditional large-displacement models - and the future by diverting into new categories. These might have Harley traditionalists looking on in horror but it's a fact that Harley has to evolve if it is to survive into the future. It's a fascinating story that isn't over yet.
