Harley Davidson FXLRS Softail Low Rider S 2021 Service Manual

Harley didn't just blacken the finishes to build the Low Rider S — the frame rake was tightened to 28 degrees, down from 30 on the standard Low Rider, delivering noticeably sharper, more responsive handling than the model it's based on. Moto-style drag bars on 4-inch risers put the rider in an aggressive, tall-bike stance, and dual front discs replace the single-disc setup on the base Low Rider for stronger braking with less lever effort.

Power comes from the Milwaukee-Eight 114, making a claimed 100 hp and 119 lb-ft of torque through a 6-speed gearbox and belt final drive, with a 4.016 in. bore and 4.5 in. stroke on a 10.5:1 compression ratio, running electronic sequential port fuel injection through a 2-into-2 offset shotgun exhaust. An inverted, single-cartridge front fork stiffens the front end for sharper steering response, while the adjustable mono-shock rear delivers dynamic cornering without giving up the hardtail look.

Dimensions run 92.7 in. long with a 63.6 in. wheelbase and 26.5 in. laden seat height. It rolls on a distinctive 110/90B19 front and 180/70B16 rear tire setup, with a 5-gallon tank and 5-quart oil capacity, shipping at 650 lbs. 2021 pricing started at $17,999 for Vivid Black, with Midnight Crimson as the only other factory color.

Ridden the way it looks like it wants to be ridden, a Low Rider S needs proper upkeep — this factory manual covers the torque specs, wiring diagrams, and procedures to keep one running the way Harley built it.
