bloody useful that, spent just a while there looking at bits that might be able to fit to the old gsxf track project (thread soon)
this could also be useful to potential mad custom builder types:

although i haven't played with it much, the basic idea is to find what part no. your bit on the bike has then cross ref with anything else that might do, very handy if you go to a breakers and are try to figure out if a part will fit.
