falco systems fit without too much hassel (I'm not sure what you mean with your 2nd question though?). If you intend to have pillions then you'll need to source the falco rear footrests and they are expensive and hard to come by, the akrapovic dual system rear footrests work as well (some drilling required in the near side footrest) but again expensive and heard to come by.
hope this helps
