Road Glide FLTRX (2021): WebBikeWorld Confirms "Unchanged From Last Year's Model" — The Base Trim Carrying the Shark-Nose Fairing Standard
WebBikeWorld's own confirmed 2021 review places this exact trim within Harley's three-tier Road Glide lineup that year: "the Road Glide is one of Harley Davidson's most popular bikes, period. The distinctive American bagger attitude is highlighted with the classic 'Sharknose' frame-mounted fairing, which is home to the standard Boom! Box GTS Infotainment System. In the 2021 Harley Davidson lineup, three versions of the Road Glide are available. Unchanged from last year's model, this first level of the Road Glide comes with the Milwaukee-Eight 107 engine, one-touch opening hard bags, Dual Daymaker Reflector LED Headlamps, and floorboards all standard."
Power comes from the Milwaukee-Eight 107, an air/oil-cooled V-twin, a 3.937-inch bore and 4.375-inch stroke, fed by fuel injection with fly-by-wire throttle, delivering a claimed 110 lb-ft of torque through a 6-speed transmission with belt final drive. WebBikeWorld's own confirmed account notes the Reflex Defensive Rider Systems technology package remained optional rather than standard on this base trim — a genuine equipment distinction worth knowing versus the pricier Special and Limited variants.
Eisenhauer's York Harley's own confirmed factory spec sheet lists a 6.8-inch trail on a 64-inch wheelbase, a 25.9-inch laden seat height, and 5.5 inches of ground clearance. Dennis Kirk's own confirmed parts reference lists 130/60B-19 front and 180/55B-18 rear tires, a 49mm fork, and a 140-tooth/24mm drive belt. That same source confirms the standard High Beach Harley dealer copy describing the fairing's genuine function: "a distinctive, menacing, mile-hungry design that cuts through the wind like no other fairing in the world."
WebBikeWorld's own confirmed 2021 colorway list runs to three options — Vivid Black, Billiard Red, and Gauntlet Gray Metallic — with pricing starting at $21,699 USD. High-performing front and rear suspension with easily adjustable rear shocks, and standard Brembo ABS brakes, round out the platform's core equipment. This FLTRX base-trim configuration ran alongside the Special (FLTRXS) and Limited (FLTRK) that same model year, sharing the fundamental Milwaukee-Eight 107 architecture with the standard Road King and Street Glide covered elsewhere in this catalog.
This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2021 Road Glide FLTRX running the way it was built to.
