For its 115th anniversary in 2018, Harley-Davidson offered selected models in two serialized blue paint schemes, and the Fat Boy 114 was the only one available in both: a two-tone Legend Blue and Vivid Black, and a matte Legend Blue Denim. Each carried a 115th Anniversary eagle emblem and badging and an embossed seat with blue stitching. Underneath it was the standard 2018 Fat Boy 114.
