Harley Davidson FXLRS Softail Low Rider S 2023 Service Manual

Harley's own dealer-confirmed product copy calls this "a blacked-out, factory custom performance cruiser" built for "rebels seeking a now classic West Coast style" — aggressive riding with sportbike-like agility and handling wrapped in moto-style drag bars.

Power comes from the Milwaukee-Eight 117, a 1,923cc air-cooled 45-degree V-twin, with a 4.075-inch bore and 4.5-inch stroke and a 10.2:1 compression ratio, fed by Electronic Sequential Port Fuel Injection through a 2-into-2 offset shotgun exhaust with catalyst-equipped mufflers, run through a 6-speed transmission. Harley's own dealer spec sheet confirms a genuinely aggressive riding position built into the equipment: a one-inch moto handlebar mounted on four-inch risers.

The tank carries genuine period-correct detailing — an FXLRS badge cover and a throwback dropped "H" logo styled after early Harley race bikes. Suspension consists of a preload-adjustable monoshock rear end paired with the model's signature front end, with confirmed dimensions listing a 63.6-inch wheelbase, 28-degree rake, 5.7 inches of trail, and a genuinely low 27-inch laden seat height (28 inches unladen). Riding on 110/90B19 front and 180/70B16 rear tires, curb weight comes in at 679 lbs in running order with a 5-gallon fuel tank.

Standard equipment includes all-LED lighting with a signature position lamp and LED Zeppelin tail lamp, a 4-inch analog tachometer with digital speedometer, gear indicator, and range display, plus standard cruise control and Harley's Smart Security System. 2023 colorways spanned Vivid Black ($18,199 base) through custom two-tone options, with a White Sand Pearl finish also offered that year.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2023 Low Rider S FXLRS running the way it was built to.
