I just bought a 2002 vstar 650 custom. I'm looking to get a sissybar so my wife feels a little more secure on it. But i was wondering if 1100 parts will fit on a 650? I know the backrest will, but I'm not sure about the mounting brackets. Someone told me most accesories should fit because 1100 and 650 have about the same body just a different motor. Anyhow, any help is appreciated.
