Bike for Engineering Project

I want to buy a bike for me to be able to work on it for one of my engineering projects. The idea is to turn it into a performance-oriented motorcycle. That being the case, I want a bike that has the potential to be so modified and made better in terms of performance. Please suggest a suitable bike for this project. Preetish Kumar Jha, Patna

You may opt for any motorcycle that you may fancy. Please remember, however, that each motorcycle requires different levels of modifications in order to enhance its performance. Therefore, some bikes will be easier than others in terms of the effort to be put in and the time spent. You may select one based on your level of expertise.
