Harley-Davidson's FLHP Road King is powered by a 1690cc, oil-cooled twin cam 103 engine. For 2009, H-D added a new chassis for more responsive maneuverability, increased capacity (a 70-pound load) and greater comfort for the rider. Incorporating an all-new frame, swingarm, engine mounting system, wheels and tires, the new chassis forms the foundation for the new police motorcycle. Wheel diameter increases to 17 inches from 16 inches. Color schemes include white and luxury blue (pictured). Photo via Harley-Davidson.
