This fender has been specifically designed to fit in conjunction with our 300 Tire Swingarm Conversion Kit for 2018-up Milwaukee Eight FLFBS Fat Boy’s and FXBRS Breakout’s.
In fact it allows the rear wheel to be offset to the right 0.4″ (or 10mm), in order to maintain the stock width belt. Made out of stainless steel it accepts 300 tires on 18×10.5 rims.
