15 years of NVH applications make Transfer Path Analysis appear a commodity tool. This is however not the case. Required insight in the application constraints makes TPA remain an expert approach. This paper reviews past progress in TPA methodology and its limitations. It then introduces a number of innovative approaches addressing these, opening new application fields. This includes speed improvement (Fast TPA), structural modeling integration (Modal Contribution Analysis), CAE integration (Hybrid TPA), sound quality interpretation (TPA-sound synthesis) and supporting better exploitation of operational data (Operational Path Analysis). An outlook is given to the next challenge, the application to transient problems.

While on the one hand the development period to meet the market needs to be as short as possible and cost reduction of products is extremely important for manufacturers, the demands for environmental considerations and riders' comfort have recently been rapidly increasing in the area of motorcycle performance as well. Considering these arguments, this paper discusses how to establish technology to predict riders' vibration comfort of a motorcycle, starting from a computer aided design (CAD). So far, only a few papers on the prediction of motorcycle vibration have already been made public, but with regard to modeling the connection between component models even less literature is available and, as a result, empirical figures are widely used. Therefor this paper focuses on the modeling aspects of these connectors to make accurate virtual models that allow the assessment of motorcycle vibrations in operational conditions.
