The 2026 Harley-Davidson® Breakout® is engineered as a long, low cruiser that combines a high-displacement Milwaukee-Eight® engine with a rigid Softail®-based chassis and integrated rider-assist technology. Its measurable output of 103 horsepower and 126 ft-lb of torque establishes a strong performance baseline, while its 240 mm rear tire, 21-inch front wheel, and extended 66.7-inch wheelbase define its stance and handling geometry. The motorcycle incorporates electronic rider safety systems, LED lighting, and a consolidated instrumentation display to support controlled operation. Every system, from drivetrain ratios to suspension travel, reflects deliberate engineering intended to balance torque delivery, stability, and braking control.
Milwaukee-Eight® 117 Custom Engine Architecture
The 2026 Harley-Davidson® Breakout® is powered by the Milwaukee-Eight® 117 Custom engine with a displacement of 117 cubic inches or 1,923 cc. This V-Twin engine uses pushrod-operated overhead valves with hydraulic, self-adjusting lifters and four valves per cylinder.
The engine features a bore of 4.075 inches and a stroke of 4.5 inches. Its 10.3 to 1 compression ratio supports controlled combustion and sustained torque production. Output is rated at 103 horsepower at 4,800 rpm and 126 ft-lb of torque at 3,000 rpm. The torque testing method follows J1349 standards, and lean angle testing follows J1168 standards. The power curve emphasizes low- to mid-range torque, aligning with cruiser-focused acceleration characteristics.
Fuel delivery is managed by Electronic Sequential Port Fuel Injection. This system meters fuel precisely to each cylinder for consistent throttle response and stable combustion. The engine uses a pressurized dry-sump lubrication system with an oil cooler to regulate operating temperatures and maintain lubrication efficiency during extended operation. The air intake utilizes a Helix-style air cleaner that supports steady airflow. Exhaust gases exit through a 2-into-2 staggered system with a catalyst integrated into the muffler.
Fuel capacity is 5 gallons, with a 1-gallon reserve indicated by a warning light. Oil capacity with the filter is 5 quarts. Transmission capacity is 1 quart, and the primary chain case holds 1.43 quarts. Estimated fuel economy is 49 mpg under city and highway testing conditions.
Six-Speed Cruise Drive® Transmission and Gear Ratios
The 2026 Harley-Davidson® Breakout® uses a 6-Speed Cruise Drive® transmission engineered to distribute power across a broad rpm range. The primary drive uses a chain with a 34 to 46 ratio. The final drive is belt-driven with a 32 to 66 ratio, reducing maintenance requirements while delivering smooth torque transfer.
Overall gear ratios are structured to support acceleration and controlled cruising. First gear carries a ratio of 9.311, followed by 6.454 in second, 4.793 in third, 3.882 in fourth, 3.307 in fifth, and 2.79 in sixth. The stepped reduction between gears allows progressive acceleration while maintaining lower engine speed in higher gears.
Clutch engagement is handled by a mechanical 10-plate wet clutch with assist and conventional functionality. This design supports controlled lever effort and consistent engagement under load.
Chassis Geometry and Structural Composition
The frame consists of mild steel tubular construction with a rectangular section backbone. It integrates stamped, cast, and forged junctions joined through MIG welding. Aluminum-forged fender supports reduce weight while preserving structural rigidity. The swingarm also uses mild steel tubular sections with a stamped cross-member and forged axle junctions. A removable belt spacer simplifies service access.
Overall length measures 93.5 inches. Overall width measures 37 inches, and overall height is 44.3 inches. The wheelbase measures 66.7 inches, contributing to straight-line stability. Rake is set at 34 degrees, with a fork angle of 36 degrees and a trail measuring 5.7 inches. This configuration provides controlled steering response within a long-wheelbase layout.
Seat height, laden, measures 25.6 inches, while seat height, unladen, measures 26.2 inches. Static ground clearance is 4.5 inches. Lean angles are rated at 26.8 degrees to both the right and left sides. These values define the operational cornering envelope for the motorcycle.
Weight as shipped is 655 pounds. Weight in running order is 681 pounds. Gross Vehicle Weight Rating is 1,175 pounds, with a front axle rating of 450 pounds and a rear axle rating of 760 pounds.
Suspension Calibration and Ride Control
The front suspension uses a 49 mm telescopic fork with dual-bending valve technology and aluminum triple clamps. The fork incorporates a dual-rate spring to manage compression under varied load conditions. Front suspension travel measures 5 inches.
Rear suspension consists of a hidden, free piston, coil-over monoshock with a 43 mm stroke and hydraulic preload adjustment. Rear travel measures 3.4 inches. The preload adjustment allows adaptation for passenger weight or additional load without altering frame geometry.
This front and rear configuration maintains controlled damping characteristics while preserving the motorcycle’s low profile. Suspension travel values are calibrated to manage surface irregularities within the constraints of a cruiser-oriented stance.
Wheel Configuration and Tire Specifications
The 2026 Harley-Davidson® Breakout® uses gloss black 26-spoke cast aluminum wheels. The front wheel measures 21 inches in diameter and 3.5 inches in width. The rear wheel measures 18 inches in diameter and 8 inches in width.
Tires are Michelin® Scorcher 11 units installed front and rear. The front tire specification is 130 over 60 B21 63H BW. The rear tire specification is 240 over 40 R18 79V BW. The 240 mm rear tire increases contact surface area, supporting torque transfer and traction during acceleration.
Braking System and Stability Controls
The braking system uses a 4-piston fixed caliper at the front and a 2-piston floating caliper at the rear. Front rotor diameter measures 11.8 inches with a thickness of 0.2 inches. The rear rotor measures 11.5 inches with a thickness of 0.23 inches. The front brake configuration is a single disc.
The anti-lock braking system is standard equipment. The motorcycle also includes a Traction Control System and a Drag-torque Slip Control System. The Tire Pressure Monitoring System is integrated to provide ongoing pressure data.
Cornering Rider Safety Enhancements expand the system's capability. Cornering Enhanced ABS, Cornering Enhanced Traction Control System, and Cornering Drag-Torque Slip Control System adjust braking and torque management based on lean angle input. Electronic Linked Braking and Enhanced Lift Mitigation are not included. Vehicle Hold Control and Wheel Lift Mitigation are also not included.
Electrical Capacity and Lighting Systems
The electrical system uses a sealed, maintenance-free absorbed glass mat battery rated at 12 volts, 17.5 amp hours, and 310 cold cranking amps at 0 degrees Fahrenheit. Charging is handled by a three-phase 48 amp system producing 364 watts at 13 volts and 900 rpm, with a maximum of 624 watts at 13 volts and 2,000 rpm.
Starting is managed by a 1.6 kW electric starter with solenoid shift motor engagement. Lighting is entirely LED-based. The headlamp provides low beam, high beam, and signature position lighting. Tail and stop lamps use bullet-style LED units. Front and rear turn signals are LED bullet units.
A USB C-Type outlet provides 5 volts at 2.4 amps for compatible devices. No auxiliary lamps, reverse system, or integrated GPS system are included.
Instrumentation and Ride Data Interface
Instrumentation consists of a 4-inch analog speedometer integrated with a digital display. The display provides gear position, odometer, fuel level, ride modes, heated gear status, traction control indicator, ABS status, TPMS data, cruise control indicator, clock, trip meters, range, and tachometer. This consolidated interface centralizes operational data within a compact gauge housing.
