2015 Harley-Davidson FLTRX Road Glide
About the 2015 Harley-Davidson FLTRX Road Glide
The 2015 Harley-Davidson FLTRX Road Glide marked the return of the 'Sharknose' fairing to the touring lineup after a one-year hiatus, featuring the comprehensive 'Project Rushmore' enhancements. This model introduced the High Output Twin Cam 103 engine, a redesigned triple-vented fairing to reduce head buffeting, and One-Touch saddlebag latches. It serves as the base trim in the Road Glide family, offering a more streamlined feature set compared to the 'Special' (FLTRXS) version.
What Makes This Trim Special
- Infotainment System — Equipped with the Boom!™ Box 4.3 system (non-touch, no GPS) compared to the 6.5GT on the Special.
- Rear Suspension — Uses traditional air-adjustable shocks instead of the hand-adjustable low-profile premium shocks found on the Special.
- Inner Fairing Finish — Features a matte/grained black plastic inner fairing, whereas the Special is painted gloss black.
- Braking System — Reflex™ Linked Brakes with ABS were an optional upgrade on the FLTRX but standard on the Special.
Likely but unverified:
- Security System — The Smart Security System with proximity fob was typically an option on the base FLTRX.

Frequently Asked Questions About the 2015 Harley-Davidson FLTRX Road Glide
No, the 2015 Road Glide does not come with a factory reverse gear. Reverse is only standard on Harley-Davidson Trike models.
Yes, it features Electronic Sequential Port Fuel Injection (ESPFI) as standard equipment.
The Special (FLTRXS) includes a larger 6.5-inch touchscreen with GPS, hand-adjustable rear shocks, standard ABS, a gloss black painted inner fairing, and pinstriping. The base Road Glide (FLTRX) has a 4.3-inch screen, air shocks, and a matte inner fairing.
The engine oil capacity is approximately 4.0 quarts (3.8 liters) with a filter change. You should also check the primary (38 oz) and transmission (32 oz) fluids during a full service.
It uses a YTX30L-BS (or H-D equivalent 66010-97D) AGM battery with at least 385-400 Cold Cranking Amps (CCA).
Yes, it comes standard with Dual Daymaker™ Reflector LED headlamps, which were a major part of the Project Rushmore lighting upgrades.
This is often caused by a poor connection at the Throttle-By-Wire (TBW) plug on the throttle body. Check for codes P1510 or P2176. Cleaning the pins and using dielectric grease often fixes it.
The base 4.3 Boom! Box does not have built-in GPS. To get factory navigation, you must upgrade the entire head unit to the 6.5GT version or use a handlebar-mounted mobile device.
