For your RoadKing, I would suggest checking out our selection of rear kits. The Fatboy Cholo Fenders are for softails without saddlebags. The rear kits are built for the bags and rear fender body lines to flow together. Here is a link: rushbikes.com/product-category/body/rear-end-kits/
Can the fat front tire on the Fatboy clear that front fender the site says it will clear a 120mm but the 2010 Fatboy I have has a 140mm in the front???
Casey Barnard: The 2013 Heritage uses a 140mm rear fender. I have a video premiering in two weeks all about the different options for the Deluxe, Heritage, and slims. Stay tuned to see all the options available. Thanks for watching
