Model-Year & Chassis Generation Notes
Stepping up from the 107 FXBB in 2021, the FXBBS 114 made two-up seating, passenger pegs, and tubeless 6-spoke Annihilator cast wheels standard alongside the 1,868cc M8 engine.
Oil & Clutch Mechanical Engineering Note
Pairing the 297 kg stripped Softail chassis with the torquey M8 114, the FXBBS isolates 4.7 L of SAE 20W-50 engine oil from its Formula+ primary bath and 6-speed gearbox.
Garage Wrenching Gotchas
- Its slim 13.2 L (3.5-gal) tank requires earlier ~200 km fuel stops than 5-gallon Softails; toggle the compact handlebar-clamp LCD strip to monitor remaining range.
- Inspect the accordion rubber fork gaiters after wet rides to make sure bottom vent holes stay clear so trapped grit does not pit inner stanchions and weep fork oil.
5. Frequently Asked Questions (FAQ)
How are engine and separate drivetrain fluid capacities split on the Harley-Davidson Street Bob 114 (FXBBS 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 Street Bob 114 (FXBBS 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 Street Bob 114 (FXBBS Softail)?
Fitted with 100/90B19 57H front and 150/80B16 77H rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 30 / 40 PSI (207/276 kPa) solo or 30 / 42 PSI loaded. Seat height is 680 mm (26.8 in) at 297 kg wet weight, delivering ~249 km per 13.2 L tank.
