4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Produced for 2020–2021, the initial Softail FXLRS shares the steep 28-degree rake, inverted fork, and dual front discs, but wears dual tank-console gauges and a Ventilator air cleaner.
Oil & Clutch Mechanical Engineering Note
Equipped with the updated high-scavenge 8-lobe M8 oil pump, the 2020–2021 FXLRS 114 runs reliably on 4.7 L of SAE 20W-50 engine oil plus isolated Formula+ primary and gearbox baths.
Garage Wrenching Gotchas
- Converting the tank-mounted dual gauges to a tall T-bar riser setup requires plug-and-play NAMZ/OEM gauge extension harnesses and sealing the tank console block-off plate.
- The upper shotgun muffler partially blocks straight socket access to the right rear axle nut; use a 36 mm offset axle wrench with a torque-wrench adapter when setting belt deflection.
5. Frequently Asked Questions (FAQ)
How are engine and separate drivetrain fluid capacities split on the Harley-Davidson Low Rider S 114 (FXLRS Softail)?
The engine sump takes 4.3 L drain-only and 4.7 L (4.97 US qt) with filter (HD 62700296 / 62700297 (HF171C)) of SAE 20W-50 (JASO MA2), while isolated drivetrain cavities (primary chaincase 1065 ml, separate gearbox 828 ml) require dedicated gear/chaincase fluid.
How do you accurately check the oil level on the Low Rider S 114 (FXLRS Softail), and what are its service intervals?
Bring the engine to full operating temperature and check the Full Hot mark with the motorcycle resting on its sidestand (Jiffy Stand) on level pavement—measuring upright leads to crankcase overfill and breather blow-by. Torque the drain plug to 24 N·m with a new crush washer. Factory oil change intervals are every 8,000 km, with valve clearance inspection every 48,000 km.
What are the cold tire pressures, puncture repair type, seat height, and range of the Low Rider S 114 (FXLRS Softail)?
Fitted with 110/90B19 62H front and 180/70B16 77H rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 30 / 38 PSI (207/262 kPa) solo or 30 / 40 PSI loaded. Seat height is 690 mm (27.2 in) at 308 kg wet weight, delivering ~340 km per 18.9 L tank.
