Classic Design with Modern Enhancements
The Harley-Davidson® Fat Boy® is known for its muscular stance and commanding presence, and the 2025 model continues that tradition with updates that highlight its bold character. The large, 18-inch machined Lakester wheels are complemented by massive tires and cutback fenders that emphasize the bike's aggressive look. These wheels, along with a new premium paint scheme and updated tank medallion, reinforce the iconic aesthetic. The new paint options include Billiard Gray, Vivid Black, Blue Burst, and Whiskey Fire/Vivid Black, all of which bring a new level of depth to the bike's design.
The headlamp nacelle, a hallmark of the Harley-Davidson® Fat Boy®, is finished in bright, polished chrome, giving the front end a powerful and bold appearance.
Engine and Performance
The 2025 Harley-Davidson® Fat Boy® is powered by the Milwaukee-Eight® 117 Custom V-twin engine, which delivers 104 horsepower and 126 lb-ft of torque. The engine is paired with an updated two-into-two exhaust system, enhancing both performance and the bike's distinctive rumble.
Suspension and Handling
Handling is an essential aspect of any motorcycle, and the 2025 Harley-Davidson® Fat Boy® offers substantial improvements in this area. The monoshock rear suspension has been recalibrated to offer greater comfort while maintaining a firm, composed ride during aggressive maneuvers.
Additionally, the dual-bending valve forks on the front provide precise handling, ensuring that the bike maintains control and stability in a variety of road conditions.
Rider Comfort and Ergonomics
The 2025 Harley-Davidson® Fat Boy® is designed to ensure that riders feel comfortable throughout their journey. The seat height of 25.9 inches provides a lower center of gravity.
Additionally, the adjustable brake lever allows riders to customize the fit, ensuring maximum efficiency regardless of hand size or reach. The hand controls have been updated to accommodate Cruise Control, Ride Modes, and Traction Control.
Technology Integration
The 2025 Harley-Davidson® Fat Boy® is equipped with modern technology that enhances the riding experience while maintaining the bike’s core focus on performance. The five-inch analog display provides clear and easy-to-read data, while an integrated digital display offers real-time information on critical features like Ride Modes. These Ride Modes allow riders to adjust the bike’s performance based on different conditions.
USB-C charging capabilities are also included, allowing riders to keep their devices powered while using navigation systems or listening to music.
Rider Safety Features
Harley-Davidson® continues to prioritize rider safety, and the 2025 Harley-Davidson® Fat Boy® comes with several advanced safety features to ensure a stable and controlled ride. The Cornering Enhanced Anti-lock Braking System (C-ABS) is a key addition, adjusting brake pressure to maintain control while cornering.
The Cornering Traction Control System (C-TCS) is another valuable feature, preventing the rear wheel from spinning excessively under acceleration.
Additional safety systems include the Drag-Torque Slip Control System (DSCS), which reduces rear-wheel slip during rapid deceleration, and the Tire Pressure Monitoring System (TPMS), which alerts the rider to low or high tire pressure.
Bold Presence on the Road
The 2025 Harley-Davidson® Fat Boy® continues to embody the bold, muscular image that has made it a staple in the Harley-Davidson® lineup. The larger, more powerful engine, along with the high-performance Michelin® Scorcher® 11 tires, ensures that the 2025 Harley-Davidson® Fat Boy® is just as impressive both in performance and appearance.
