The 2026 Harley-Davidson® Breakout® is a factory-built cruiser that combines large-displacement V-Twin power, a long-wheelbase chassis, advanced rider safety technologies, and distinctive wheel and tire specifications. Designed around the Milwaukee-Eight® 117 Custom engine, the 2026 Harley-Davidson® Breakout® integrates a 6-Speed Cruise Drive® transmission, electronic fuel injection, a steel tubular frame, and a range of electronic rider-assistance systems. The motorcycle also incorporates LED lighting, comprehensive rider information displays, and modern control technologies that contribute to its overall functionality.
Engine and Powertrain
The 2026 Harley-Davidson® Breakout® is powered by the Milwaukee-Eight® 117 Custom engine, a large-displacement V-Twin engineered to deliver substantial torque and horsepower. This engine features a bore of 4.075 inches and a stroke of 4.5 inches, resulting in a total displacement of 117 cubic inches, or 1,923 cubic centimeters. A compression ratio of 10.3:1 supports the engine's combustion characteristics and performance output. Harley-Davidson® rates the engine at 126 ft-lb of torque at 3,000 rpm and 103 horsepower, or 77 kW, at 4,800 rpm.
Valve Train and Fuel Delivery
The Milwaukee-Eight® 117 Custom engine uses a pushrod-operated overhead valve configuration with hydraulic self-adjusting lifters. Each cylinder contains four valves, creating a valve train layout designed to support efficient airflow through the combustion chambers. Fuel is supplied through Electronic Sequential Port Fuel Injection (ESPFI), which electronically meters fuel delivery according to engine operating requirements. This fuel system works in conjunction with a Helix-style air cleaner that manages incoming airflow.
Exhaust and Lubrication Systems
The exhaust system on the 2026 Harley-Davidson® Breakout® uses a 2-into-2 staggered configuration. A catalyst is integrated into the muffler assembly as part of the exhaust design. Engine lubrication is handled by a pressurized dry-sump system equipped with an oil cooler. This arrangement stores and circulates oil independently from the crankcase while providing dedicated cooling support for the lubrication system.
Drivetrain and Transmission
The drivetrain of the 2026 Harley-Davidson® Breakout® transfers engine output through a combination of chain and belt drive components. The primary drive uses a chain with a 34/46 ratio, while the final drive utilizes a belt with a 32/66 ratio. This arrangement forms the mechanical link between the engine and the rear wheel.
Clutch and Gear Ratios
Power transfer is managed through a mechanical 10-plate wet clutch that incorporates assist and conventional operation. This clutch assembly works in conjunction with the 6-Speed Cruise Drive® transmission, providing six forward gears for acceleration, cruising, and general riding operation. The overall gear ratios are 9.311 in first gear, 6.454 in second gear, 4.793 in third gear, 3.882 in fourth gear, 3.307 in fifth gear, and 2.79 in sixth gear. These progressively spaced ratios provide a structured transition through the transmission's operating range.
Chassis and Structural Design
The chassis of the 2026 Harley-Davidson® Breakout® is constructed around a mild steel tubular frame. The frame incorporates a rectangular-section backbone along with stamped, cast, and forged junctions that are joined using MIG welding. Aluminum forged fender supports are also integrated into the overall structure. This frame design provides the foundational architecture that supports the motorcycle's dimensions, geometry, suspension components, and powertrain.
Swingarm Construction
The swingarm is manufactured from mild steel tubular sections and incorporates a stamped cross member. Forged axle junctions contribute to the assembly, and MIG welding is used throughout the construction process. The swingarm also includes a removable belt spacer as part of its design. Together, the frame and swingarm create the structural platform that supports the rear suspension and final drive system.
Dimensions and Geometry
The 2026 Harley-Davidson® Breakout® measures 93.5 inches in length, 37 inches in overall width, and 44.3 inches in overall height. The wheelbase measures 66.7 inches, creating a substantial footprint between the front and rear axles. Steering geometry includes a 34-degree rake and a 36-degree fork angle. Trail is specified at 5.7 inches, or 145 mm. Static ground clearance measures 4.5 inches, while seat height is 25.6 inches laden and 26.2 inches unladen.
Suspension, Wheels, and Tires
The suspension system combines telescopic front suspension technology with a concealed rear monoshock arrangement. The front fork is a 49 mm dual-bending valve telescopic unit equipped with aluminum fork triple clamps and a dual-rate spring. Front suspension travel measures 5 inches, or 130 mm.
Rear Suspension Design
At the rear, the motorcycle utilizes a hidden free-piston coil-over monoshock. The shock features 43 mm of stroke and includes hydraulic preload adjustment capability. Rear wheel travel measures 3.4 inches, or 86 mm. The concealed design contributes to the motorcycle's overall packaging while retaining rear suspension functionality. Hydraulic preload adjustment allows the rear suspension setup to be adjusted through the shock assembly.
Wheel and Tire Specifications
The 2026 Harley-Davidson® Breakout® uses gloss black 26-spoke cast aluminum wheels at both ends. The front wheel measures 21 inches in diameter and 3.5 inches in width, while the rear wheel measures 18 inches in diameter and 8 inches in width. Tire equipment consists of Michelin® Scorcher 11 tires front and rear. The front tire specification is 130/60B21,63H,BW, and the rear tire specification is 240/40R18,79V,BW.
Braking Systems and Control Technologies
The braking system on the 2026 Harley-Davidson® Breakout® combines fixed and floating caliper designs with floating brake rotors. The front brake uses a four-piston fixed caliper, while the rear brake uses a two-piston floating caliper. Front and rear braking surfaces consist of black Split 7-spoke floating rotors. The front rotor measures 11.8 inches in diameter and 0.2 inches in thickness, while the rear rotor measures 11.5 inches in diameter and 0.23 inches in thickness.
Anti-Lock Braking and Stability Systems
Anti-Lock Braking System functionality is included as standard equipment. The motorcycle also incorporates a Traction Control System and Drag-Torque Slip Control System. Tire Pressure Monitoring System functionality is included as part of the rider-assistance package. These systems work together to provide electronic support for braking, traction management, and tire-pressure monitoring during operation.
Cornering Rider Safety Enhancements
The 2026 Harley-Davidson® Breakout® also includes Cornering Enhanced Anti-Lock Brake System technology. Cornering Enhanced Traction Control System and Cornering Drag-Torque Slip Control System functionality are also included. These systems expand the motorcycle's rider safety technology package through cornering-sensitive electronic controls.
Electrical System and Instrumentation
The electrical system utilizes a sealed, maintenance-free absorbed glass mat battery rated at 12 volts and 17.5 amp-hours. The battery is specified at 310 cold cranking amps at 0°F. Electrical charging is supplied through a three-phase 48-amp charging system. Output is rated at 364 watts at 13 volts and 900 rpm, with maximum power output of 624 watts at 13 volts and 2,000 rpm. Starting duties are handled by a 1.6 kW electric starter system with solenoid shift starter motor engagement.
LED Lighting Systems
Lighting throughout the motorcycle utilizes LED technology. The headlamp assembly incorporates LED low beam, high beam, and signature position lamp functions. Tail and stop lighting use bullet-style LED stop, tail, and turn signal components. Front turn signals utilize LED Bullet Turn Signals, while rear turn signals also employ LED Bullet Turn Signals.
Rider Information Display
Instrumentation is centered around a 4-inch analog speedometer with integrated digital information displays. The digital system provides gear position indication, odometer readings, fuel level information, ride mode information, heated gear status, traction control status, ABS status, and TPMS information. Additional displayed functions include cruise control status, clock, trip information, range information, and tachometer readings. This integrated instrumentation package consolidates multiple vehicle functions within a single rider-facing display area. A USB-C-Type power outlet providing 5V output at 2.4 amps is also included as part of the motorcycle's equipment package.
