I saw some on ebay, I searched engine guards in parts and accessories and just put in Roadstar Silverado S and it not only came up with a lot of different engine guards, but also the hard bag guards that would go on my 2013 Roadie... I am pretty sure they would also go on a 2012, not sure about the 2004, I think that bike is a little different but it doesn't hurt to look up part numbers and compare?

Sometimes it's harder to challenge yourself,
then to face the challenge it's self.
