2018 Harley-Davidson FLTRXS Road Glide Special
About the 2018 Harley-Davidson FLTRXS Road Glide Special
The 2018 Harley-Davidson FLTRXS Road Glide Special is a premium bagger featuring the frame-mounted 'shark nose' fairing and the Milwaukee-Eight 107 V-Twin engine. This model year marked a significant shift for the Special trim, moving from chrome to a full blacked-out aesthetic and introducing the larger 18-inch rear Talon wheel. It serves as the more aggressive, custom-styled alternative to the standard Road Glide, coming factory-equipped with upgraded infotainment and stretched saddlebags.
What Makes This Trim Special
- Blacked-out Finishes — Engine covers, exhaust, front forks, handlebars, and trim are finished in black instead of chrome.
- Talon Wheels — Black multi-spoke Talon cast aluminum wheels; 19-inch front and 18-inch rear (standard model used 16-inch rear).
- Stretched Saddlebags — Saddlebags extend lower over the exhaust for a slammed custom look.
- Boom! Box 6.5GT Infotainment — Standard 6.5-inch full-color touchscreen with navigation and voice activation.
- Painted Inner Fairing — The inner fairing is finished in high-gloss black rather than the matte plastic found on base models.
