Milwaukee-Eight® 117 Engine Configuration and Output
The 2026 Harley-Davidson® Breakout® is equipped with a Milwaukee-Eight® 117 Custom engine, configured with a displacement of 117 cubic inches, equivalent to 1,923 cubic centimeters. The engine uses a bore of 4.075 inches and a stroke of 4.5 inches, forming a long-stroke configuration that supports torque generation at lower engine speeds. A compression ratio of 10.3 to 1 contributes to combustion efficiency while maintaining operational consistency.
The engine produces 126 foot-pounds of torque at 3,000 revolutions per minute and generates 103 horsepower at 4,800 revolutions per minute. This output is achieved through a pushrod-operated overhead valve system that incorporates hydraulic, self-adjusting lifters. Each cylinder contains four valves, supporting airflow management and combustion efficiency.
Fuel delivery is managed by an Electronic Sequential Port Fuel Injection system, which meters fuel precisely based on engine demand. Air intake is supported by a Helix-style air cleaner, which is designed to optimize airflow into the combustion chamber. The exhaust system follows a 2-into-2 staggered configuration with a catalyst integrated into the muffler, ensuring compliance with emissions requirements while maintaining exhaust flow characteristics.
The lubrication system is a pressurized dry-sump design that includes an oil cooler. This configuration separates oil storage from the crankcase and helps maintain stable operating temperatures during extended operation. The engine does not use liquid cooling, relying instead on air-cooled and oil-assisted temperature regulation.
Drivetrain Integration and Gear Ratio Calibration
Power from the engine is transmitted through a chain-driven primary system with a 34 to 46 ratio. The final drive uses a belt system with a 32 to 66 ratio, which reduces maintenance requirements and ensures consistent power transfer. This combination supports durability while maintaining efficient energy delivery from the engine to the rear wheel.
The transmission is a 6-Speed Cruise Drive® system, designed to provide a wide range of gear ratios for different operating conditions. The gear ratios are structured to support both acceleration and highway cruising. First gear has a ratio of 9.311, while sixth gear is set at 2.79. Intermediate gears are spaced progressively, allowing for smooth transitions and controlled engine speed across the rev range.
A mechanical clutch system with ten plates operates in a wet configuration and includes assist functionality. This reduces lever effort and improves engagement consistency. The drivetrain system works as a unified assembly, ensuring that torque output from the engine is translated into forward motion without excessive loss or vibration.
Frame Construction and Suspension Mechanics
The frame of the 2026 Harley-Davidson® Breakout® is constructed from mild steel using a tubular design with a rectangular section backbone. The structure integrates stamped, cast, and forged junctions, which are joined through MIG welding. Aluminum forged fender supports are included to reduce weight while maintaining structural integrity.
The swingarm is also constructed from mild steel and uses tubular sections with a stamped cross-member. Forged axle junctions enhance durability, and the design includes a removable belt spacer to facilitate maintenance.
Front suspension is managed by a 49 millimeter telescopic fork that incorporates dual-bending valve technology. This design uses a dual-rate spring system to control compression and rebound characteristics. Rear suspension consists of a hidden coil-over monoshock with a free piston design. The rear unit provides 43 millimeters of stroke and includes hydraulic preload adjustment, allowing the rider to modify suspension response based on load conditions.
Suspension travel measures 5 inches at the front and 3.4 inches at the rear. These values are calibrated to balance ride comfort with handling precision, particularly given the motorcycle’s long wheelbase and low stance.
Wheel Dimensions and Tire Specifications
The 2026 Harley-Davidson® Breakout® uses a wide rear tire configuration that influences both traction and visual proportions. The front tire is specified as 130/60B21, mounted on a 21-inch wheel with a width of 3.5 inches. The rear tire measures 240/40R18 and is mounted on an 18-inch wheel with a width of 8 inches. Both tires are Michelin® Scorcher 11 models, selected for their grip characteristics and durability.
The wheels are gloss black, 26-spoke cast aluminum units. This construction balances strength and weight while maintaining consistent rotational stability. The large rear tire increases the contact patch, improving traction during acceleration. The front wheel diameter supports directional control and contributes to the overall geometry of the motorcycle.
Braking System and Controlled Deceleration
The braking system is configured with a 4-piston fixed caliper at the front and a 2-piston floating caliper at the rear. The front rotor measures 11.8 inches in diameter, while the rear rotor measures 11.5 inches. Both rotors use a split 7-spoke floating design, which assists in heat dissipation and reduces the risk of brake fade during repeated use.
Anti-lock Braking System functionality is included as standard. This system modulates braking force to prevent wheel lock during sudden or aggressive braking. The configuration is designed to maintain directional control and stability under varying surface conditions.
Electrical System and Rider Interface
The electrical system uses a sealed, maintenance-free absorbed glass mat battery rated at 12 volts and 17.5 amp-hours. It provides 310 cold cranking amps at zero degrees Fahrenheit. Charging is handled by a three-phase, 48-amp system that delivers up to 624 watts of maximum power at 2,000 revolutions per minute.
Starting is performed by a 1.6 kilowatt electric starter that uses a solenoid shift engagement system. Lighting is fully LED-based, including the headlamp, tail lamp, and turn signals. The headlamp incorporates a low beam, a high beam, and a signature position lamp.
Instrumentation is centered on a 4-inch analog speedometer combined with a digital display. The display provides information such as gear position, odometer, fuel level, ride modes, traction control status, ABS indicators, tire pressure monitoring system data, cruise control settings, clock, trip distance, range, and tachometer readings. A USB C-type power outlet is included, providing 5 volts at 2.4 amps for device charging.
Safety Systems and Cornering Control Features
The 2026 Harley-Davidson® Breakout® includes a range of rider safety systems that enhance control during operation.

A Drag-torque Slip Control System is also included, which helps manage rear wheel behavior during downshifting.
A Tire Pressure Monitoring System provides continuous feedback on tire pressure levels, allowing the rider to maintain optimal tire performance. Cornering enhancements are integrated into several of these systems. Cornering Enhanced ABS adjusts braking force based on lean angle, while Cornering Traction Control and Cornering Drag-torque Slip Control provide similar adjustments during cornering conditions.
The motorcycle has a lean angle capability of 26.8 degrees on both the left and right sides. This specification reflects the balance between cruiser geometry and cornering performance.
Fuel Capacity and Efficiency Metrics
The fuel tank has a capacity of 5 gallons, with a reserve indicator that activates when approximately 1 gallon remains. This capacity supports extended riding distances without frequent refueling. The estimated fuel economy is 49 miles per gallon, based on combined city and highway testing.
Fluid capacities include 5 quarts of engine oil with a filter, 1 quart for the transmission, and 1.43 quarts for the primary chain case. These values ensure that all major systems operate within their designed lubrication parameters.
