Harley-Davidson® of Washington, DC - Why the Milwaukee-Eight® 117 Custom Makes the 2025 Harley-Davidson® Fat Boy® Shine for Fort Washington, MD Riders
When a cruiser earns its reputation on torque, feel, and road presence, any engine update has to move the needle in ways you can actually feel. That is exactly what the Milwaukee-Eight® 117 Custom does for the 2025 Harley-Davidson® Fat Boy®. The power comes on with a confident surge from low rpm, the midrange is bolder for quick passes, and the cadence at highway speed settles into an easy rhythm. It is the sort of refinement you notice on your first commute and appreciate even more during a long Saturday loop. Combined with a high-flow two-into-two exhaust, the 117 breathes better, sounds richer, and delivers that classic V-twin character with a polished edge.
What stands out most is the way the engine’s personality supports the Fat Boy®’s identity. This bike is about commanding stance and effortless motion — and the 117 leans into both. The throttle feels predictable and responsive, so threading through town is easy, yet the moment you open it up onto open roads, the bike steps forward with authority. Pair that with the updated monoshock rear suspension, and you get a cruiser that rides calmer over choppy pavement while staying planted in fast sweepers. Tech touches — a Five-Inch Analog Display with an integrated digital readout, selectable Ride Modes, Traction Control, and USB-C charging — add modern convenience without stealing the spotlight.
- Real-world torque: Strong low and midrange pull makes urban riding and highway passes equally relaxed.
- Refined cadence: Calmer cruising rpm helps reduce fatigue on longer stretches.
- Balanced character: A richer exhaust note complements the engine’s broader breathing without overwhelming the ride.
If your checklist includes classic style, authentic sound, and performance you can use every day, the Milwaukee-Eight® 117 Custom is the upgrade that ties the whole package together. It keeps the Fat Boy® unmistakably itself, only more capable and more composed across the board.
