The target of this thesis work is to provide a fast and realistic simulation tool able to evaluate and compare different set up of a motorcycle during race weekend and the target area on which the vehicle development has to focus. It represents the integration of the digital tools developed along the previous race seasons inside the 2WheelsPolito team. The experience gained suggested that simulation and calculation of the ideal trajectory with a perfect ride behavior and theoretical vehicle set up, often will not bring advantages and will be impossible to apply it on a real rider and bike. Instead the tool presented, relying on a real Log, will help the team to maximize the performance, customizing the analysis and tailoring the results on each rider peculiarity.
