Road King™

Road King™

In Brief

The Hiawatha headlamp and nacelle were born in the ‘60s, but the power of the Milwaukee-Eight® 107 engine on the Road King® brings it all into right now, fast. The Showa® dual-bending valve front suspension and rear emulsion shocks put riders in control for a plush ride. And riders get cast Impeller wheels and one-touch bags. It’s a modern classic.
