From 2012 the Road Glide Custom moved up to the Twin Cam 103 engine with an integrated oil cooler and a 2-1-2 dual exhaust, giving more pulling power with the same low, slammed bagger look, 18-inch front wheel and frame-mounted fairing. It continued in this form through 2013, after which the Road Glide range was paused for the 2014 Project Rushmore overhaul.
