These were the Nightster's last two years in its original 1200 Evolution form. The recipe stayed the same: blacked-out Dark Custom styling, a bobbed rear fender with side-mount plate, gaitered fork and a low seat. It was dropped after 2012, and the Nightster name later resurfaced on an all-new liquid-cooled 975 cc bike.
