Every year new Harley – what drives the people?????

Personally, I can’t understand it (independently of the fact that you burn a lot of coal every time you buy a new product with the payment of the old HD), those are looking for which still THE right Harley or have to drive the latest model as with your mobile phone (some also always pick up the same model)????
