4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Introduced for 2025 to succeed the Ultra Limited, the FLHXU combines the new batwing fairing, center-radiator M8 117, storage lower fairings, and King Tour-Pak while shedding ~23 kg.
Oil & Clutch Mechanical Engineering Note
Replacing twin lower-fairing radiators with a single low-mounted center radiator for the cylinder heads, the FLHXU preserves traditional 3-Hole isolated engine, primary, and gearbox oils.
Garage Wrenching Gotchas
- Road grit off the front fender packs into the low center radiator core; blow debris out gently from behind at every oil change to preserve summer head-cooling efficiency.
- Accessing the deep-set 28Ah AGM battery requires pulling the seat and ECM caddy; connect a smart AGM maintainer directly to the factory SAE tender pigtail behind the left side cover.
5. Frequently Asked Questions (FAQ)
How are engine and separate drivetrain fluid capacities split on the Harley-Davidson Street Glide Ultra 117 (FLHXU)?
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 Ultra 117 (FLHXU), 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 Ultra 117 (FLHXU)?
Fitted with 130/60B19 M/C 61H front and 180/55B18 M/C 80H rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 36 / 40 PSI (248/276 kPa) solo or 36 / 42 PSI loaded. Seat height is 725 mm (28.5 in) at 393 kg wet weight, delivering ~375 km per 22.7 L tank.
