4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Upgraded in 2022 from 114 to the 1,923cc M8 117, the FXLRS relocated instrumentation from the tank console to a handlebar-riser gauge and fitted a taller rear monoshock for extra lean angle.
Oil & Clutch Mechanical Engineering Note
Ridden aggressively in West Coast club-style trim, the oil-cooled M8 117 thrives on full-synthetic SYN3 20W-50 filled ~75% up the hot sidestand dipstick range to curb breather misting.
Garage Wrenching Gotchas
- Unlike single-disc Softails, the inverted-fork FXLRS runs dual front rotors requiring two pad sets, and specifies a lower 30 PSI (207 kPa) cold front tire pressure.
- Note that 2025-up updates revise exhaust routing into a factory 2-into-1 setup and expand ride-mode electronics—always match slip-on brackets and ECM calibrations to exact model year.
5. Frequently Asked Questions (FAQ)
How are engine and separate drivetrain fluid capacities split on the Harley-Davidson Low Rider S 117 (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 117 (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 117 (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 710 mm (28.0 in) at 308 kg wet weight, delivering ~336 km per 18.9 L tank.
