In its last Twin Cam 88 years the 2005-2006 Road King Classic gained a lighter-effort clutch and fresh colour options while keeping its five-speed, fuel-injected drivetrain. Wide whitewall tyres on steel laced wheels, leather-wrapped hard saddlebags, auxiliary lamps and a detachable windshield continued to define it as the nostalgic member of the Road King family.
