The implementation of lightweight design in motorcycle development has utmost priority. This paper offers various examples of how structural durability can be ensured in combination with a lightweight concept. In order to consistently implement a lightweight philosophy, the weight potential of each individual component must be carefully analysed. Optimised geometries and use of materials push components to the limits of their durability while guaranteeing an excellent power-toweight ratio. To achieve this high standard of durability, it is essential to accurately reproduce the loads encountered on the road during simulation and testing. The load data required for this purpose is obtained by measuring such loads using vehicles specially prepared and solely used for measuring. Simulated service load tests are conducted on multi-axial test rigs specially developed for motorcycles to validate experimentally the suspension, frame and handlebars. Fast, low cost uni-axial, constant amplitude tests are also employed to examine component deviation and possible derivatives. Special events and misuse loads must also be considered during the measurement and validation of components. To ensure optimum lightweight construction it is crucial to apply and maintain a consistent design, calculation and validation process in product development during the entire process. To further reduce the weight, magnesium alloys and plastics, including carbon-fibrereinforced plastics, may also be used for load-bearing structures. In this case the experimental validation tests conducted must also take the special properties of such materials into account, for example by simulating environmental conditions in an appropriate manner.
