2017 Harley-Davidson FLHRXS Road King Special
About the 2017 Harley-Davidson FLHRXS Road King Special
The 2017 Road King Special is a stripped-down, custom bagger that marked the first year of the Milwaukee-Eight 107 engine in a blacked-out aesthetic. It differs from the standard Road King by ditching chrome for a dark, aggressive look, featuring larger wheels, and removing the factory windshield. This model year is significant as it introduced the 4-valve-per-cylinder M8 platform, offering 10% more torque and improved heat management over the previous Twin Cam 103.
What Makes This Trim Special
- Blacked-out Styling — Engine covers, exhaust, handlebars, front forks, and headlight nacelle are finished in black instead of chrome.
- Stretched Saddlebags — Bags wrap lower around the mufflers for a slammed appearance; includes one-touch latches.
- Turbine Wheels — 19-inch front and 18-inch rear black cast aluminum wheels (Standard Road King uses 17/16-inch).
- Mini-Ape Handlebars — 9-inch tall black bars for a more aggressive riding posture.
- Windshield Removal — The Special shuns the standard Road King's detachable windshield for a cleaner profile.

Frequently Asked Questions About the 2017 Harley-Davidson FLHRXS Road King Special
No, it does not have a factory reverse gear. It is a traditional two-wheeled motorcycle.
The Special features blacked-out components, stretched saddlebags, larger 19/18-inch wheels, and mini-ape bars, and it lacks the standard model's windshield and passing lamps.
A standard service oil change with filter typically requires 4.5 to 4.75 quarts of oil.
