4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Built for 2022–2023, the FLHXST mates the batwing chassis with the 1,923cc air/oil-cooled M8 117, standard-bottom bags for cornering clearance, trimmed front fender, and solo saddle.
Oil & Clutch Mechanical Engineering Note
Its high-capacity Assist & Slipper clutch handles 168 Nm inside the isolated primary bath; stick to measured H-D Formula+ (900–1,065 ml wet refill) for crisp engagement and easy neutral.
Garage Wrenching Gotchas
- Because FLHXST shipped solo from the factory, riders adding passenger pegs and a two-up seat must dial up the left-side hydraulic rear preload knob before carrying a pillion.
- All M8 engines run four HD 6R10 dual-spark plugs; lift the rear of the fuel tank or use a thin-wall swivel socket to reach the inner top plugs without cracking porcelain insulators.
5. Frequently Asked Questions (FAQ)
How are engine and separate drivetrain fluid capacities split on the Harley-Davidson Street Glide ST 117 (FLHXST)?
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 Street Glide ST 117 (FLHXST), 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 Street Glide ST 117 (FLHXST)?
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 710 mm (28.0 in) at 369 kg wet weight, delivering ~377 km per 22.7 L tank.
