Key Features of the 2025 Harley-Davidson® Street Bob®

Milwaukee-Eight® 117 Classic V-twin

The new Milwaukee-Eight® 117 Classic is tuned to deliver strong, immediate thrust across the rev range, producing a broad, flat torque curve that is ideal for real-world riding. Its displacement and calibration are engineered for crisp response off the line and confident passing power, with precisely timed valve events that support both power and refinement. The engine’s cooling strategy and internal balancing contribute to a smooth, satisfying pulse at cruise while retaining the unmistakable Harley-Davidson® character at idle. Paired with the updated intake and an efficient exhaust, the 117 Classic provides the kind of torque-rich surge that makes every on-ramp and two-lane pull feel effortless.

Two-into-one Exhaust

The Street Bob® now runs a new two-into-one exhaust designed to optimize gas flow while trimming mass. Inside, a lightweight acoustic material helps maintain throughput without muting the signature sound, resulting in a deep, muscular note that underscores the engine’s intent. On the road, this exhaust complements the 117 Classic’s torque delivery, helping the bike build speed with satisfying urgency. The system’s packaging also preserves lean angle and ground clearance, supporting confident cornering on winding routes while keeping the lines of the motorcycle clean and purposeful.

SHOWA® Dual Bending Valve Front Suspension

Front-end poise comes from improved SHOWA® Dual Bending Valve technology, which provides more consistent damping across a wider range of fork travel. The result is better control over bumps, less dive under braking, and a planted, predictable feel mid-corner. Paired with a rear monoshock using an under-seat, cam-style pre-load adjuster, riders can quickly set sag for solo, two-up, or light cargo, maintaining geometry and ride height with minimal effort. Together, the suspension package delivers comfort on the highway and composure when you pick up the pace, making the Street Bob® feel sure-footed and responsive.

Four-inch Display with Ride Modes

The rider interface blends classic and modern with a large analog gauge mounted over an LCD screen. This four-inch display gives you quick access to Ride Modes, Rider Safety Enhancements settings, and essential ride data without clutter. Updated hand controls improve ergonomics and simplify navigation of the interface, making it easy to tailor performance to conditions or preference. Integrated support for in-helmet audio and Bluetooth® helps you manage music and calls, and the USB-C charging port keeps your smartphone powered for navigation or communication. It is a clean, functional cockpit that elevates everyday usability without sacrificing the minimalist look.

LED Lighting and Visibility

Lighting upgrades are both aesthetic and functional. A 5.75-inch LED headlight projects a wide, bright white beam to illuminate the road ahead, improving clarity on dark backroads and early morning commutes. LED turn signals provide crisp, highly visible signaling to help other motorists track your intentions. These elements complement the Street Bob® silhouette and add peace of mind, emphasizing visibility and presence in a way that aligns with the motorcycle’s modern performance and classic stance.
