The 2025 Harley-Davidson® Street Bob® is a bobber-style motorcycle engineered to balance power, handling, and modern technical features. It retains the stripped-down bobber aesthetic with a slim profile and minimalistic design while incorporating updates to its engine, suspension, safety systems, and rider interface. The technical specifications of the 2025 Harley-Davidson® Street Bob® reflect the commitment of Harley-Davidson® to improving performance and rider control.
Engine and Exhaust: Milwaukee-Eight® 117 Classic V-Twin Specifications
The Milwaukee-Eight® 117 Classic engine serves as the driving force behind the motorcycle, offering 98 horsepower and 120 foot-pounds of torque. This naturally aspirated V-Twin is built for consistent, real-world performance, from traffic to open roads. Its torque curve remains flat across the rev range, allowing riders to access usable power without needing to push into high RPMs. Acceleration is immediate and controlled, contributing to a ride that feels both responsive and composed.
The engine incorporates a two-into-one exhaust system constructed with lightweight acoustic materials intended to maximize exhaust flow efficiency. This design supports improved engine breathing and contributes to a deep exhaust rumble. Fuel efficiency for the 2025 Harley-Davidson® Street Bob® is rated at approximately 47 miles per gallon, balancing power output with fuel economy.
Chassis and Suspension: Handling and Rider Comfort
The 2025 Harley-Davidson® Street Bob® uses an updated suspension setup to enhance ride quality and control. The front suspension consists of SHOWA® dual-bending valve 49 mm forks. These forks provide damping characteristics aimed at improving stability over uneven road surfaces and during cornering maneuvers. The rear suspension utilizes a monoshock positioned under the seat with cam-style preload adjustment. This design allows riders to adjust suspension firmness to compensate for varying loads and road conditions, maintaining a controlled and comfortable ride.
The chassis geometry supports agile handling while maintaining stability at higher speeds. Wheel sizes are 19 inches at the front and 16 inches at the rear, offering a bobber-style silhouette with functional benefits for maneuverability and ride quality.
Wheels and Tires: Design and Functionality
Wheels on the 2025 Harley-Davidson® Street Bob® come in two configurations: blacked-out cast Annihilator wheels or tubeless laced wheels. The tubeless laced wheels blend traditional bobber styling with modern tubeless tire benefits, including ease of maintenance and improved safety in the event of a puncture. The tires are Dunlop® Harley-Davidson® Series, engineered to provide grip and durability appropriate for various riding conditions.
Lighting Systems: LED Technology and Visibility
Lighting components have been upgraded to LED technology across the 2025 Harley-Davidson® Street Bob®. The headlight is a 5.75-inch LED unit delivering a broad, bright white light pattern. This headlamp enhances visibility and rider safety in low-light or nighttime conditions. The turn signals use clear LED modules designed to be highly visible to other motorists. The LED system reduces power consumption compared to traditional bulbs and offers a longer service life.
Rider Interface and Instrumentation: Display and Controls
The 2025 Harley-Davidson® Street Bob® features a four-inch multifunction display that combines an analog gauge with an LCD screen. This setup presents critical ride information clearly and allows the rider to access different ride modes and safety feature settings. The display is designed for easy readability in varying lighting conditions.
Hand controls have been updated to improve ergonomics and allow direct management of ride modes and safety enhancements without distraction. The controls support intuitive operation and integrate smoothly with the bike’s electronic systems.
A USB-C charging port is included to maintain power for connected devices such as Bluetooth® headsets or navigation units, enabling extended use of technology on rides.
Rider Safety Systems: Electronic Aids and Monitoring
The Rider Safety Enhancements package on the 2025 Harley-Davidson® Street Bob® incorporates several electronic systems designed to maintain control and traction in diverse conditions. The Anti-lock Brake System (ABS) is calibrated to prevent wheel lock during hard braking, helping preserve directional stability. Traction Control System (TCS) works to prevent rear-wheel spin during acceleration, increasing stability on slippery surfaces.
The Drag-Torque Slip Control System (DSCS) reduces rear-wheel slip during abrupt downshifts or throttle changes, particularly useful on wet or uneven roads. Cornering variants of these systems adjust their intervention based on lean angle, providing tailored support during turns to maintain traction and braking balance.
A Tire Pressure Monitoring System (TPMS) alerts the rider when tire pressure falls outside recommended ranges, supporting optimal tire performance and safety.
Paint, Styling, and Ergonomics: Maintaining Bobber Identity with Functional Updates
The bike’s paint options include Billiard Gray, Vivid Black, Centerline, Iron Horse Metallic, and Purple Abyss Denim. Each features the “stretched diamond” tank medallion, a design element rooted in Harley-Davidson® heritage from 1966. The slim 3.5-gallon gas tank and mini ape-hanger handlebars contribute to the minimalist bobber aesthetic, as does the bobbed rear fender.
The round black-and-chrome air intake complements the classic look while supporting engine breathing. The bike’s ergonomic setup includes mid-mounted foot controls designed to provide a neutral riding posture suitable for urban and open-road riding.
Integrated Performance: Balancing Power, Handling, and Rider Control
The combination of the Milwaukee-Eight® 117 engine, suspension components, and electronic rider aids equips the 2025 Harley-Davidson® Street Bob® to deliver controlled power and handling. The dual-bending valve front suspension works with the adjustable rear monoshock to smooth out road irregularities and maintain tire contact during dynamic riding.
The electronic safety systems intervene only as needed, allowing experienced riders to maintain control while providing assistance to avoid loss of traction or braking instability. The chassis and wheel configuration supports confident cornering and straight-line stability.
