Key Features of the 2025 Harley-Davidson® Breakout®

Milwaukee-Eight® 117 Custom Powertrain

The heart of the 2025 Breakout® is the Milwaukee-Eight® 117 Custom, tuned to deliver intense acceleration off the line and commanding passing power on demand. A generously oversquare feel and optimized breathing support strong midrange thrust, while the new touring intake contributes to high-flow performance. Throttle response is crisp, with smooth fueling that shines in low-speed maneuvering and heavy traffic. On the open road, the engine relaxes into a steady cadence, making long stretches feel effortless. Refinement is evident at every RPM, helped by internal balancing and engine mounting that filter harshness without muting the classic V-Twin character. Pair it with the Two-Into-Two Exhaust, and you get not only strong performance but also a muscular, balanced soundtrack that complements the bike’s long-and-lean aesthetic.

240mm Rear Tire and 34-Degree Chopper-Style Rake

The Breakout® wears its heritage proudly, centering the design around a wide 240mm rear tire and a 34-degree Chopper-Style Rake. The visual effect is unmistakable: a long, purposeful profile that looks custom the moment it rolls into view. What sets the 2025 model apart is how the chassis geometry and trail are tuned to work with that wide tire, maintaining a broad contact patch under acceleration while delivering nimble, predictable steering at typical street speeds. The 21-inch front wheel is highlighted by a single 300mm front disc that preserves the open, airy look while providing confident stopping power. It is chopper style done the modern way, where form and function are carefully balanced so the motorcycle handles as good as it looks.

Two-Into-Two Exhaust

Clean lines, deep tone, and free-breathing performance define the Two-Into-Two Exhaust on the Breakout®. It traces the motorcycle’s silhouette without visual clutter, reinforcing the long, low profile. Internally, flow is optimized to support the engine’s high-torque goals while keeping unwanted resonance in check. The result is a strong, satisfying growl that never overwhelms on longer stints. Because the system maintains efficient scavenging, roll-on response feels immediate, especially in the midrange. It’s an exhaust that respects classic cruiser design while delivering the performance the Milwaukee-Eight® 117 Custom deserves.

Hydraulic Preload-Adjustable Rear Monoshock

Under the seat, a hydraulic preload adjuster lets you dial in the rear monoshock for rider weight or added cargo in moments. The adjuster’s convenient placement encourages riders to optimize setup regularly, which pays dividends in ride quality and control. With correct preload, cornering composure improves, rear tire grip is more consistent, and small-bump compliance stays supple. Whether you are carving familiar routes or carrying weekend gear, proper setup maximizes the Breakout® chassis. Combined with the tuned front end and the wide rear tire’s generous contact patch, the suspension ensures the bike treads steadily in sweepers and remains responsive in tighter city maneuvers.

Four-Inch Analog Display, Ride Modes, and Rider Safety Enhancements

The Four-Inch Analog Display blends an easy-to-scan speedometer with a digital screen that presents Ride Modes, trip data, and vital stats at a glance. The interface keeps the cockpit clean and fits the classic-chopper vibe, yet it unlocks modern versatility on every ride. Integrated Rider Safety Enhancements include dynamic ABS and Traction Control designed to help manage variable grip in changing conditions. New ergonomic hand controls and a quickly adjustable front brake lever let you tailor reach and feedback. USB-C charging sits close at hand to power a phone or GPS, a practical touch if you’re using navigation or a Bluetooth® headset. Together, these systems deliver a tech-forward experience without stealing attention from the bike’s mechanical soul.
