The 2025 Harley-Davidson Softail lineup received the most significant update to the platform since the Milwaukee-Eight engine was introduced. While the bikes retain their classic styling, nearly every model gained more power, better suspension, and substantially more technology.
2025 Softail Models
The 2025 lineup was streamlined to six models:
- Street Bob
- Heritage Classic
- Fat Boy
- Breakout
- Low Rider S
- Low Rider ST
The Fat Bob was discontinued for 2025.
1. All Models Now Get the Milwaukee-Eight 117
For 2025, every Softail is powered by a 117 cubic-inch (1,923 cc) engine. In 2024, some models used the 107 or 114.
Three distinct versions of the 117 are used:
- 117 Classic – Street Bob and Heritage Classic
- 117 Custom – Fat Boy and Breakout
- 117 High Output – Low Rider S and Low Rider ST
This means stronger acceleration and more torque across the entire lineup, with the High Output versions producing approximately 114 horsepower.
2. New Four-Valve Cylinder Heads and Improved Cooling
The 2025 117 engines feature:
- New four-valve cylinder heads
- Revised intake manifold
- Updated exhaust systems
- Improved cylinder-head cooling
These changes increase power while helping the engine run more efficiently.
3. Ride Modes (A Softail First)
For the first time, all Softails include selectable ride modes:
- Road
- Rain
- Sport (on applicable models)
Ride modes adjust throttle response, traction control, and braking intervention.
4. Cornering Rider Safety Enhancements
All 2025 Softails now include lean-sensitive electronic aids such as:
- Cornering ABS
- Cornering Traction Control
- Drag-Torque Slip Control
- Tire Pressure Monitoring System (TPMS)
- Cruise Control
These are major additions, bringing touring-bike-level electronics to the cruiser lineup.
5. Retuned Suspension
Harley-Davidson revised both front and rear suspension with single-rate springs replacing progressive springs. The result is:
- Smoother ride quality
- Reduced harshness
- More predictable braking dive
- Better front-to-rear balance
Travel remains unchanged, but the bikes feel more refined on real-world roads.
6. New Controls and Displays
Updates include:
- Adjustable brake levers
- New switchgear
- LCD multifunction display integrated with the analog speedometer
This modernizes the rider interface while preserving traditional Harley styling.
7. All-LED Lighting and USB-C Charging
Every model now comes with:
- Full LED lighting
- USB-C charging port
- Relocated heated-gear connectors under the seat
These practical upgrades improve everyday usability.
Best 2025 Softail Upgrades for Buyers
If you’re selling these motorcycles, the most compelling customer benefits are:
- 117 engine standard across the lineup
- Ride modes and cornering safety technology
- TPMS and cruise control
- Improved suspension comfort
- Modern conveniences like USB-C and LED lighting
Sales Perspective
The 2025 Softails are especially attractive to riders who appreciate classic Harley design but want modern performance and safety. Customers who previously considered adding aftermarket upgrades now get many premium features directly from the factory.
Bottom Line
The 2025 Softail lineup represents one of Harley-Davidson’s biggest cruiser updates in years. The motorcycles look familiar, but beneath the surface they deliver more power, significantly better technology, and improved ride quality. For many buyers, the 2025 models are compelling enough to justify choosing new over a discounted 2024.
