The engine produces a certified torque output of 72 ft-lb at 5,750 rpm and a power rating of 91 horsepower at 7,500 rpm. Bore measures 3.82 inches and the stroke measures 2.6 inches. A compression ratio of 12:1 supports efficient combustion and contributes to engine responsiveness at mid and upper RPM ranges. Fuel delivery is managed through Electronic Sequential Port Fuel Injection, which regulates fuel flow precisely based on throttle input and operating conditions. The engine uses a semi-dry sump lubrication system designed to maintain consistent oil delivery during acceleration, braking, and cornering.
Air intake design includes downdraft intake routing with tuned velocity stacks and washable filter media. The exhaust configuration uses a 2-into-1 layout with a catalyst integrated into the header assembly. This arrangement promotes efficient exhaust flow while meeting emission requirements. Combined engineering choices result in a powertrain designed for balanced performance and predictable torque delivery.
Transmission and Drivetrain Engineering
Power from the Revolution® Max 975T engine flows through a mechanical drivetrain designed for smooth engagement and stable operation. The primary drive uses a gear-based system with a 49/89 ratio. Final drive is managed through a belt system with a 34/80 ratio. This arrangement reduces routine maintenance requirements and maintains consistent power transfer characteristics over time.
The motorcycle uses a six-speed transmission configured to support acceleration in lower gears and efficient cruising in higher gears. Overall gear ratios are calibrated progressively, beginning with a short first gear ratio of 12.21 and decreasing through each gear to a sixth gear ratio of 4.131. The clutch is an eight-plate wet mechanical design with assist and slip functionality. This system reduces clutch lever effort and improves rear wheel stability during aggressive downshifts. The result is smoother gear transitions and controlled deceleration characteristics.
Chassis Architecture and Structural Design
The chassis of the 2026 Harley-Davidson® Nightster® uses a stressed-member design incorporating a high-strength low-alloy steel trellis frame. Stamped, cast, and forged components are combined through MIG welding to create structural rigidity while controlling weight. An aluminum forged mid-structure contributes to mass reduction and supports improved handling response. This design approach allows the engine to function as a structural element, contributing to overall stiffness and reducing unnecessary material.
The swingarm is constructed from mild steel using a rectangular tube section with a stamped cross-member. This configuration provides stability under load while maintaining predictable suspension movement. Weight figures show a shipped weight of 462 pounds and a running order weight of 481 pounds. The gross vehicle weight rating is 922 pounds, with separate front and rear axle ratings supporting load distribution consistency. These figures illustrate the model’s focus on maintaining a lightweight profile without compromising structural capability.
Suspension Setup and Handling Geometry
Front suspension is provided by a 41 mm SHOWA® Dual Bending Valve conventional fork with aluminum triple clamps. This fork design improves damping control by managing pressure distribution inside the fork during compression and rebound. The front suspension travel measures 4.5 inches, supporting stability during braking and on uneven road surfaces.
Rear suspension uses dual outboard direct-acting emulsion shock absorbers equipped with coil springs. A threaded collar allows preload adjustment to accommodate varying rider loads. Rear suspension travel measures 3 inches. The combination of front and rear suspension components is tuned to maintain balanced weight transfer and stable handling across city streets and highway speeds.
Wheel construction consists of aluminum cast units finished in satin black. The front wheel measures 19 inches in diameter and 2.5 inches in width. The rear wheel measures 16 inches in diameter and 4.25 inches in width. Tire specifications include a 100/90-19 front tire and a 150/80B16 rear tire from the Dunlop® Harley-Davidson® Series. These dimensions support predictable steering response while maintaining rear traction stability.
Braking Systems and Rider Safety Features
