4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Produced for 2022–2023, the King of the Baggers-inspired FLTRXST brought the air/oil-cooled M8 117, taller standard-height rear shocks, solo saddle, and Heavy Breather intake to a factory bagger.
Oil & Clutch Mechanical Engineering Note
Running an exposed Heavy Breather intake and high-output cam in an oil-cooled M8 117, full-synthetic SYN3 20W-50 engine oil and 80W-140 gear oil best protect lifters and 6-speed dogs under hard riding.
Garage Wrenching Gotchas
- Do not over-oil the exposed Heavy Breather cone element after washing, and install the OEM water-repellent rain sock when riding or parking in heavy downpours.
- After pulling the quick-release hard saddlebags, keep both rear axle weldment cams aligned identically before torquing the 36 mm axle nut to 135–149 Nm to eliminate belt chirp.
5. Frequently Asked Questions (FAQ)
How are engine and separate drivetrain fluid capacities split on the Harley-Davidson Road Glide ST 117 (FLTRXST)?
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 Road Glide ST 117 (FLTRXST), 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 Road Glide ST 117 (FLTRXST)?
Fitted with 130/60B19 61H front and 180/55B18 80H rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 36 / 40 PSI (248/276 kPa) solo or 36 / 40 PSI loaded. Seat height is 715 mm (28.1 in) at 382 kg wet weight, delivering ~375 km per 22.7 L tank.
