28. HARLEY-DAVIDSON ROAD KING
THE FACTS O 111ftlb O 379kg O Seat height 705mm
The FL family of tourers, including everything from the Street Glide and Road King to the full-dress Ultra Glide, all get a new 107 Milwaukee-eight engine for 2017 – and it’s rather good.
To boost performance and efficiency, the new Milwaukee-eight is not just larger-capacity (1745cc from 1690cc) but now has four-valve heads, each with twin spark plugs. These hotterrunning heads need a more efficient cooling system, so a subtle oil cooler is used on the naked baggers (such as the Road King here), while the faired
full-dressers, such as the Glide, get liquid-cooled heads. The result is more torque, power and fuel economy.
The engine and gearbox are also smoother, too, without losing that Harley character. The Road King is a rolling icon, and it just got even better.
