The 2026 Harley-Davidson® Breakout® combines a stretched cruiser layout with a high-displacement V-twin engine, large-diameter wheels, and integrated electronic rider assistance systems. The model uses the Milwaukee-Eight® 117 Custom engine paired with a 6-Speed Cruise Drive® transmission and belt final drive. Its chassis dimensions, wheel configuration, suspension geometry, and braking systems are designed to support straight-line stability and low-rpm torque delivery. The motorcycle also incorporates standard rider safety technologies, including ABS, traction control, drag-torque slip control, and cornering-enhanced systems.
Milwaukee-Eight® 117 Custom Engine Configuration
The 2026 Harley-Davidson® Breakout® uses a Milwaukee-Eight® 117 Custom engine with a displacement of 117 cubic inches, or 1,923 cc. The engine features a bore of 4.075 inches and a stroke of 4.5 inches. Compression ratio is rated at 10.3:1. Harley-Davidson® equips the engine with pushrod-operated overhead valves and hydraulic self-adjusting lifters. Each cylinder contains four valves.
Fuel delivery comes through Electronic Sequential Port Fuel Injection. The intake system uses a Helix-style air cleaner. Exhaust routing is handled through a 2-into-2 staggered exhaust system with a catalyst integrated into the muffler assembly. Lubrication uses a pressurized dry-sump system with an oil cooler.
The engine produces 126 ft-lb of torque at 3,000 rpm and 103 horsepower at 4,800 rpm. These output figures place emphasis on low- and mid-range acceleration characteristics. The torque curve supports lower-rpm operation during highway cruising and urban riding conditions. The engine also uses an air-cooled configuration, eliminating the need for a liquid cooling system and coolant reservoir.
Six-Speed Transmission and Drivetrain Layout
The drivetrain configuration includes a chain-driven primary system with a 34/46 ratio and a belt-driven final drive using a 32/66 ratio. The transmission is a 6-Speed Cruise Drive® unit designed for highway-speed efficiency and reduced engine rpm during higher-speed operation.
The clutch system is a mechanical 10-plate wet clutch with assist and conventional functionality. This setup is engineered to maintain clutch engagement consistency while reducing clutch lever effort under acceleration loads.
Gear ratios are configured to provide broad torque access across the rev range. First gear carries a 9.311 overall ratio, second gear uses 6.454, third gear uses 4.793, fourth gear uses 3.882, fifth gear uses 3.307, and sixth gear uses 2.79. The ratio spread supports low-speed maneuvering while maintaining lower engine speed in top gear during highway operation.
Extended Chassis Dimensions and Cruiser Geometry
The 2026 Harley-Davidson® Breakout® uses a stretched chassis profile with an overall length of 93.5 inches. Overall width measures 37 inches, and overall height measures 44.3 inches. The motorcycle has a wheelbase of 66.7 inches, contributing to its extended cruiser proportions.
Steering geometry includes a 34-degree rake and a 36-degree fork angle. The trail measurement is 5.7 inches. These figures contribute to directional stability and gradual steering response characteristics associated with long-wheelbase cruiser motorcycles.
Seat height measures 25.6 inches in laden configuration and 26.2 inches in unladen configuration. Static ground clearance is listed at 4.5 inches. Lean angle capability is rated at 26.8 degrees on both the right and left sides.
Weight as shipped is 655 pounds, while running-order weight is 681 pounds. The gross vehicle weight rating is 1,175 pounds. The front gross axle weight rating is 450 pounds, and the rear gross axle weight rating is 760 pounds.
Structural Frame and Suspension Engineering
The frame uses a mild steel tubular structure with a rectangular-section backbone. Harley-Davidson® integrates stamped, cast, and forged junctions throughout the frame assembly. The frame also incorporates MIG welding and forged aluminum fender supports.
The swingarm uses mild steel tubular sections combined with forged axle junctions and a stamped cross-member structure. The swingarm assembly also includes a removable belt spacer.
The front suspension uses a 49 mm telescopic fork with dual-bending valve technology and aluminum triple fork clamps. The fork system incorporates dual-rate springs designed to manage compression response during acceleration and braking transitions. Front suspension travel measures 5 inches.
The rear suspension uses a hidden free-piston coil-over monoshock with hydraulic preload adjustment. Rear suspension stroke is listed at 43 mm, and total rear suspension travel measures 3.4 inches. The concealed rear shock layout maintains the motorcycle’s low-profile appearance while supporting rear-wheel movement under varying load conditions.
Wheel Specifications and Tire Dimensions
The wheel configuration combines a 21-inch front wheel with an 18-inch rear wheel. Both wheels use gloss black 26-spoke cast aluminum construction. The front wheel width measures 3.5 inches, while the rear wheel width measures 8 inches.
The front tire specification is 130/60B21 63H BW. The rear tire specification is 240/40R18 79V BW. Harley-Davidson® equips the 2026 Harley-Davidson® Breakout® with Michelin® Scorcher 11 tires at both ends.
The wide rear tire contributes to the motorcycle’s extended cruiser stance and rear traction characteristics. The large-diameter front wheel supports the model’s stretched visual profile and steering geometry configuration.
Braking Hardware and Rider Assistance Systems
The braking system uses a 4-piston fixed front caliper and a 2-piston floating rear caliper. The front rotor diameter measures 11.8 inches with a rotor thickness of 0.2 inches. The rear rotor diameter measures 11.5 inches with a thickness of 0.23 inches.
The 2026 Harley-Davidson® Breakout® uses black split 7-spoke floating brake rotors at both ends. The front braking system is configured as a single-disc setup rather than dual front discs.
An anti-lock braking system is included as standard equipment. The 2026 Harley-Davidson® Breakout® also includes Traction Control System, Drag-torque Slip Control System, and Tire Pressure Monitoring System functionalities.
Cornering rider safety systems are integrated into the motorcycle’s electronic management package. These systems include the Cornering Enhanced Anti-Lock Braking System, the Cornering Enhanced Traction Control System, and the Cornering Drag-Torque Slip Control System. These systems are designed to support traction and braking management during cornering operations.
Instrumentation and Electrical Components
The 2026 Harley-Davidson® Breakout® uses a 4-inch analog speedometer combined with a digital information display. The display provides readouts for gear position, odometer, fuel level, ride modes, heated gear status, traction control, ABS status, Tire Pressure Monitoring System data, cruise control, clock, trip information, range estimation, and tachometer information.
The electrical system uses a sealed absorbed glass mat battery rated at 12 volts, 17.5 amp-hours, and 310 cold cranking amps at 0°F. Charging is handled through a three-phase 48-amp system producing 364 watts at 13 volts and 900 rpm, with maximum output reaching 624 watts at 13 volts and 2,000 rpm.
The starting system uses a 1.6 kW electric starter with solenoid shift starter motor engagement.
Lighting components use LED technology throughout the motorcycle. The headlamp assembly includes low beam, high beam, and signature position lighting. Front and rear turn signals use LED bullet-style units. The taillight and stop lamps also use LED bullet-style lighting.
A USB-C power outlet is included with a 5V output at 2.4 amps. GPS navigation, reverse functionality, Bluetooth® connectivity, infotainment systems, intercom capability, and integrated audio systems are not included on the 2026 Harley-Davidson® Breakout®.
Fuel Capacity and Operational Specifications
Fuel capacity is rated at 5 gallons, with reserve fuel warning activation occurring at approximately 1 gallon remaining. Estimated fuel economy is listed at 49 mpg under estimated city and highway testing methods.
Oil capacity with filter measures 5 quarts. Transmission fluid capacity measures 1 quart, and primary chain case capacity measures 1.43 quarts.
The 2026 Harley-Davidson® Breakout® uses Michelin® Scorcher 11 tires, a belt final drive, and a low-profile suspension configuration to support highway cruising and straight-line acceleration characteristics. Combined with the Milwaukee-Eight® 117 Custom engine, the drivetrain and chassis package emphasizes low-rpm torque delivery, long-wheelbase stability, and integrated electronic rider assistance technologies.
