Road Glide Limited FLTRK (2021): The Range-Topping Touring Flagship, Running a Genuinely Larger Front Wheel Than Its Special Sibling
Dennis Kirk's own confirmed parts reference reveals a genuine, meaningful hardware distinction separating this trim from the Road Glide and Road Glide Special covered elsewhere in this catalog: this Limited runs 130/70B-18 front and 180/55B-18 rear tires — an 18-inch front wheel, versus the 19-inch front fitted to the standard FLTRX and Special FLTRXS — a real, checkable difference worth knowing before ordering wheel or tire parts. That same source confirms an AG-ATX30-RS battery and a non-sealed drive chain shared across the range.
Power comes from the Milwaukee-Eight 114, a rubber-mounted V-twin displacing 1,868cc, fed through fly-by-wire throttle control, delivering drive through a 6-speed transmission with belt final drive (140-tooth, 24mm width) — genuinely the same fundamental engine as the Road Glide Special sharing this catalog, positioned here as the top-tier configuration within Harley's 2021 Road Glide lineup.
As the genuine flagship Road Glide trim, the Limited sits above the base FLTRX and the Special FLTRXS, adding Harley's most comprehensive standard touring equipment package — the Boom! Box GTS infotainment system, premium audio, comprehensive luggage capacity, and the brand's highest-spec chrome or Dark finish options, all built around the same frame-mounted Sharknose fairing that defines the Road Glide's distinctive silhouette across every trim in the range.
Dennis Kirk's own confirmed fork specification lists a 49mm diameter, a genuine 140-tooth drive belt, and CR9EIX spark plugs — consistent hardware shared across the wider Milwaukee-Eight 114-powered Touring lineup that year, including the Road King Special and Street Glide Special covered elsewhere in this catalog. This Limited trim represents the genuine top of Harley's 2021 Touring range for buyers wanting the fullest factory equipment package without stepping up to the pricier CVO line.
This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2021 Road Glide Limited FLTRK running the way it was built to.
