The 2015 Road King continued the Rushmore-era package unchanged in substance: High Output Twin Cam 103, six-speed Cruise Drive gearbox, dual halogen lamps and one-touch hard bags. It remained the windshield-only, no-fairing tourer in H-D's line, aimed at riders who want long-distance comfort with classic looks.
