Well im in the process of building two bikes. One for street and one for track only. I have been reading some of the treads and looking for information on some of the weight savings / parts I can do with out on my track bike. So far I plan to use vortex clip ons, rear sets, and front stay. I will also be using fiberglass fairings. Most of those parts are givens. I just need help or advice as to what other stock parts can be eliminated.
