2020 Harley-Davidson FLHX Street Glide
About the 2020 Harley-Davidson FLHX Street Glide
The 2020 Harley-Davidson Street Glide is a definitive 'hot-rod bagger' featuring the iconic fork-mounted Batwing fairing and a stripped-down profile. This model year is notable for making ABS a standard feature and introducing the optional Reflex Defensive Rider Systems (RDRS) technology suite. It serves as the baseline touring model, powered by the Milwaukee-Eight 107 engine, and received an updated 18-inch rear wheel for 2020.
What Makes This Trim Special
- Chrome Finishes — The standard FLHX features chrome engine covers, exhaust, and trim, unlike the blacked-out Special model.
- Enforcer II Wheels — Equipped with machined aluminum Enforcer II wheels (19" front, 18" rear).
- Milwaukee-Eight 107 — Powered by the 107ci engine; the Special and CVO models receive the 114ci and 117ci versions respectively.
- Standard ABS — ABS became standard equipment for the FLHX in the 2020 model year.
Likely but unverified:
- RDRS Option — The Reflex Defensive Rider Systems (traction control, cornering ABS, hill hold) was a $995 factory option.

Frequently Asked Questions About the 2020 Harley-Davidson FLHX Street Glide
Yes, for the 2020 model year, Harley-Davidson made ABS standard on the FLHX Street Glide.
The standard (FLHX) has the 107ci engine and chrome trim, while the Special (FLHXS) has the 114ci engine, blacked-out trim, stretched saddlebags, and the Boom! Box GTS infotainment system as standard.
Yes, the Boom! Box GTS system supports Apple CarPlay, though it requires a wired connection and a headset/WHIM (Wireless Headset Interface Module) to be active.
It typically takes about 4.5 to 5.0 quarts of 20W-50 oil with a filter change. Always check the level when the engine is hot.
RDRS stands for Reflex Defensive Rider Systems, a suite of electronic aids including cornering ABS, traction control, and hill-start assist. It was an optional upgrade for the standard 2020 Street Glide.
Common causes include loose fairing bolts or worn rubber isolators. Check the four main mounting bolts inside the fairing and the headlight bucket mount.

Harley-Davidson recommends changing the transmission fluid every 20,000 miles, though many owners choose to do it every 10,000 miles or annually.
