The aim of this paper is to build a framework of the motorcycle business in Germany, which can be used to construct a quantitative System Dynamics (SD) simulation model thereof. The problem to be examined is the superannuation and further aging of the motorcycle rider population in Germany and its influence on the whole market. We have chosen to concentrate on Germany the second largest European motorcycle market as it is representative of most other developed motorcycle markets. A Causal Loop Diagram of the problem is developed in a step by step, walkthrough fashion. A discussion of the cohort effect with propose possible levers for change are also introduced.
