Key Features of the 2026 Harley-Davidson® Breakout®

Milwaukee-Eight® 117 Custom

The heart of the Breakout is a Milwaukee-Eight® 117 Custom V-Twin with a 4.075-inch bore and 4.5-inch stroke delivering a displacement of 117 cu in. Tuned for street authority, it produces 126 ft-lbs of engine torque (at 3,000 rpm) and 103 HP (77 kW at 4,800 rpm), translating to immediately accessible thrust for passing, merging, or pulling from low rpm in taller gears. Electronic Sequential Port Fuel Injection (ESPFI) sharpens throttle response, while the 2-into-2 staggered exhaust with a catalyst in the muffler complements the engine’s broad power curve with a deep, performance-oriented note. Backed by robust gear ratios across the six-speed box and a chain primary (34/46 ratio), the 117 Custom brings flexible, confident acceleration that feels equally at home rolling down main street or unwinding the throttle on open two-lane stretches.

34-Degree Rake and Long Wheelbase

A defining element of the Breakout’s character is its long-and-low geometry: 34 degrees of rake, 66.7 inches of wheelbase, and a 5.7-inch trail. That geometry does more than frame the bike’s attitude — it stabilizes the chassis at speed, steadies the bike under throttle, and encourages a smooth, deliberate steering feel that suits its power-cruiser mission. Dual-bending valve 49 mm forks with aluminum triple clamps manage initial compliance and mid-stroke control, while the hidden, free-piston, coil-over monoshock (with hydraulic preload adjustment) allows you to fine-tune for rider weight or passenger/luggage. The result is a planted ride that complements the engine’s torque delivery and rewards clean, predictable inputs when you arc through long sweepers or navigate uneven pavement.

240mm Rear Tire and 21-Inch Front Wheel

The Breakout’s stance hinges on a boldly profiled 240/40R18 rear tire and a slim 130/60B21 front, mounted on gloss black 26-spoke cast aluminum wheels. This setup does two things: it anchors the bike visually and mechanically, enhancing straight-line stability and traction during strong acceleration; and it preserves precise steering feedback via the tall 21-inch front. Paired with Michelin® Scorcher 11 rubber front and rear, the bike transmits a clear road feel and maintains composure under spirited throttle. Braking is managed by a 300 mm front disc with a 4-piston fixed caliper and a 2-piston floating rear, tied to the bike’s ABS and cornering systems for consistent stops. The combination of wheel sizes and tire profiles gives the Breakout its unmistakable silhouette while supporting the kind of confident handling riders expect from a modern performance cruiser.

Rider Safety Enhancements with Cornering Control

Harley-Davidson® Rider Safety Enhancements come standard to support smoother, more predictable control when conditions get complicated. An anti-lock brake system (ABS) helps prevent wheel lock during straight-line braking. Traction Control System (TCS) manages rear-wheel spin during straight-line acceleration. Drag-Torque Slip Control System (DSCS) reduces excessive rear-wheel slip or lock-up under abrupt deceleration or downshifts. Tire Pressure Monitoring System (TPMS) alerts you to out-of-range pressures that can affect handling and tire life. Cornering Enhanced Anti-lock Brake System (C-ABS) adapts braking to lean angle; Cornering Enhanced Traction Control System (C-TCS) refines traction management while turning; and Cornering Drag-Torque Slip Control System (C-DSCS) further smooths deceleration events mid-corner. These systems do not replace rider skill, but they add a layer of confidence that’s especially welcome on variable roads or during quick changes in pace.

4-Inch Analog Gauge with Customizable Ride Modes

Minimalist and informative, the 4-inch analog speedometer integrates a digital display for gear position, odometer, fuel level, ride modes, heated gear, traction control, ABS status, TPMS readouts, cruise control indicator, clock, trip meters, range, and tachometer. The customizable ride modes let you tailor throttle response and intervention levels to your preferred feel, whether you’re riding in busy corridors or opening it up on open roads. A USB-C port streamlines device charging, while full LED lighting — headlamp, signature position lamp, and bullet-style LED turn signals — improves conspicuity and crisp nighttime visibility. It’s a thoughtfully composed cockpit that preserves a clean, custom look without sacrificing the core data you rely on while riding.
