These figures indicate strong torque availability early in the rev range, supporting acceleration without frequent high-rpm operation. The engine torque testing method follows J1349 standards, ensuring consistency in measurement. Overall, the engine setup prioritizes controlled delivery of power rather than peak high-rpm performance, aligning with the performance cruiser category.
Transmission and Drivetrain Engineering
Power transfer from the engine to the rear wheel relies on a combination of chain and belt systems. The primary drive uses a chain with a 34/46 ratio, while final power delivery uses a belt drive with a 32/66 ratio. The belt system reduces maintenance needs compared with chain-only designs and supports quieter operation during highway cruising.
The transmission is a 6-Speed Cruise Drive® unit. Gear ratios are calibrated to deliver strong acceleration in lower gears while reducing engine speed at highway velocities. The overall gear ratios include 9.311 in first, 6.454 in second, 4.793 in third, 3.882 in fourth, 3.307 in fifth, and 2.79 in sixth gear. These ratios create gradual spacing between gears and maintain consistent torque multiplication as speed increases.
The clutch uses a mechanical 10-plate wet assist and conventional design. The assist mechanism reduces lever effort during operation, which improves rider comfort during frequent shifting or urban riding. Combined with the wide torque curve of the engine, the drivetrain provides predictable engagement and controlled acceleration across varying riding conditions.
Chassis Design and Structural Components
The chassis construction uses a mild steel tubular frame with a rectangular section backbone. The structure incorporates stamped, cast, and forged junctions joined by MIG welding techniques. Aluminum forged fender supports reduce additional weight while maintaining structural rigidity. This design approach emphasizes stability and long-term durability under torque load.
The swingarm also uses mild steel tubular sections combined with forged axle junctions and a stamped cross-member. The removable belt spacer supports drivetrain alignment and serviceability. The long geometry is reflected in the 66.7-inch wheelbase, which contributes to directional stability during straight-line riding and steady cornering.
Steering geometry includes a 34-degree rake and a 36-degree fork angle, with 5.7 inches of trail. These measurements result in predictable steering input and reduced sensitivity to abrupt handlebar movement. The design favors stability over quick directional change, which aligns with the overall cruiser configuration.
Dimensions include an overall length of 93.5 inches, a width of 37 inches, and a height of 44.3 inches. The laden seat height measures 25.6 inches, while the unladen seat height measures 26.2 inches. Ground clearance is listed at 4.5 inches. These figures create a low seating position that supports rider balance during starts and stops while maintaining sufficient clearance for standard riding angles.
Suspension Systems and Ride Control
The front suspension uses a 49 mm telescopic fork with dual-bending valve technology and dual-rate springs. Aluminum fork triple clamps support strength and weight management. This front system provides a balance of responsiveness and controlled damping during braking and directional changes.
The rear suspension consists of a hidden coil-over monoshock with a free piston design. Hydraulic preload adjustment allows the rider to modify suspension settings to accommodate varying loads and rider preferences. Rear shock stroke measures 43 mm. Suspension travel measures 5 inches at the front and 3.4 inches at the rear. These values support steady handling while maintaining the low-profile appearance associated with the 2026 Harley-Davidson® Breakout® design language.
Wheel, Tire, and Contact Patch Specifications
The wheel configuration emphasizes both stability and traction. The front wheel is a gloss black 26-spoke cast aluminum unit measuring 21 inches in diameter and 3.5 inches in width. The rear wheel uses the same cast aluminum construction with a diameter of 18 inches and a width of 8 inches.
Tire specifications include a 130/60B21 front tire and a wide 240/40R18 rear tire, both using Michelin® Scorcher 11 models. The wide rear tire increases surface contact during acceleration and supports traction under torque load. The combination of a narrow front and wide rear profile influences handling characteristics by promoting straight-line stability and controlled steering response.
Braking System and Stability Assistance
The braking system uses a single front rotor with a 4-piston fixed caliper and a rear rotor with a 2-piston floating caliper. Front rotor diameter measures 11.8 inches with a thickness of 0.2 inches, while the rear rotor measures 11.5 inches with a thickness of 0.23 inches. Both rotors use a floating split 7-spoke design finished in black.
Anti-lock Braking System functionality is included as standard equipment. The braking setup focuses on predictable stopping performance without linked braking features. This configuration supports rider control by allowing independent front and rear brake input.
Lean angle capability measures 26.8 degrees on both the left and right sides. The symmetry indicates a balanced chassis setup and consistent cornering geometry. The lean angle figures align with the low stance of the motorcycle while maintaining practical riding capability.
