The last of the Twin Cam 88 Road Kings, still offered with a carburettor or fuel injection and the familiar five-speed gearbox. It kept the two-piece touring seat, footboards, detachable windshield and locking saddlebags, and came ready for cruise control. For 2006 Harley added a lighter clutch, clear-lens auxiliary lamps and a stronger 50-amp charging system.
