Engine and Powertrain
The 2026 Harley-Davidson® Pan America® 1250 ST is powered by the Revolution® Max 1250 engine, a liquid-cooled powerplant with a displacement of 1,252 cc, or 76.4 cubic inches. The engine features a bore of 105 mm and a stroke of 72.3 mm, creating a configuration designed to support high-performance operation across a broad rpm range. A compression ratio of 13.0:1 contributes to the engine's output characteristics and forms an important part of its overall design. The engine is rated at 150 horsepower, or 112 kW, at 8,750 rpm and produces 94 ft-lb of torque at 6,750 rpm. These figures establish the 2026 Harley-Davidson® Pan America® 1250 ST as a motorcycle with a clearly defined performance profile supported by measurable output specifications.
Valve Train and Induction System
The Revolution® Max 1250 engine utilizes a chain-driven dual overhead camshaft configuration with hydraulic self-adjusting lifters. Both the intake and exhaust systems incorporate variable valve timing, allowing the engine to manage airflow through changing operating conditions. Four valves per cylinder support efficient intake and exhaust flow, contributing to the engine's overall performance characteristics. Fuel delivery is managed through Electronic Sequential Port Fuel Injection, commonly identified as ESPFI.
Exhaust and Lubrication Design
The exhaust system uses a 2-into-1-into-1 configuration and incorporates a catalyst within the header assembly. This arrangement integrates exhaust routing and emissions-related components into a compact design. Engine lubrication is managed through a semi-dry sump system, which forms part of the overall engine architecture. Oil capacity with filter is listed at 4.75 quarts, while coolant capacity is 2.2 liters.
Drivetrain and Transmission
The drivetrain of the 2026 Harley-Davidson® Pan America® 1250 ST is designed to transfer engine output through a combination of gear-driven and chain-driven components. Primary drive uses a gear arrangement with a 49/89 ratio, while the final drive is handled by a chain system using a 19/48 ratio. This configuration establishes a direct mechanical connection between the engine and the rear wheel. The motorcycle employs a mechanical assist-and-slip clutch featuring an eight-plate wet design. The clutch specification includes a 1090N rating and is paired with a 6-speed transmission.
Gear Ratio Configuration
The transmission uses six forward gears with clearly defined overall ratios. First gear is listed at 13.11, providing the largest multiplication of engine torque within the gearbox. The remaining ratios are 9.687 in second gear, 7.509 in third gear, 6.057 in fourth gear, 5.08 in fifth gear, and 4.436 in sixth gear. The combination of these gear ratios, the primary drive, and the chain final drive forms the complete drivetrain package used on the 2026 Harley-Davidson® Pan America® 1250 ST.
Chassis and Structural Engineering
The chassis architecture of the 2026 Harley-Davidson® Pan America® 1250 ST centers around a stressed-member design that integrates the engine into the motorcycle's overall structure. The frame is constructed from high-strength low-alloy steel in a trellis configuration and incorporates stamped, cast, and forged junctions. Manufacturing methods include MIG welding, while an aluminum forged mid-structure contributes additional rigidity and structural support. This design creates a framework intended to support both handling precision and durability. The swingarm is a one-piece cast aluminum unit that complements the frame's blend of steel and aluminum construction.
Steering Geometry and Dimensions
The motorcycle utilizes a steering geometry package that includes a 25-degree rake and a matching 25-degree fork angle. The trail is measured at 3.7 inches, contributing to the motorcycle's steering characteristics. The wheelbase measures 62.2 inches, establishing the distance between the front and rear wheel contact patches. Overall length is 88.2 inches, while overall width is 35.3 inches, and overall height is 52.4 inches. Ground clearance is listed at 6.7 inches, providing consistent dimensional specifications across the model configuration.
Wheels and Tires
The 2026 Harley-Davidson® Pan America® 1250 ST rides on satin black cast aluminum wheels measuring 17 inches in diameter at both ends. The front wheel is 3.5 inches wide, while the rear wheel measures 5.5 inches in width. Tire selection consists of Michelin® Scorcher "Sport" models designed specifically for this application. The front tire specification is 120/70ZR17 58W, and the rear tire specification is 180/55ZR17 73W. Together, the wheel and tire package form a key component of the motorcycle's handling and chassis system.
Suspension and Ride Control
The suspension system of the 2026 Harley-Davidson® Pan America® 1250 ST combines electronic preload management with manually adjustable damping functions. This arrangement allows multiple suspension settings to be integrated into the motorcycle's chassis design. Both front and rear suspension components are designed to work together as a coordinated system. Suspension travel is 170 mm at both ends of the motorcycle.
Front Suspension
The front suspension uses a 47 mm inverted fork equipped with electronically adjustable preload. Compression damping and rebound damping adjustments are managed manually. Aluminum fork triple clamps form part of the front-end assembly and support the fork structure. The inverted fork design places larger fork components higher in the assembly and contributes to the motorcycle's chassis layout. The front suspension provides 6.7 inches of travel.
Rear Suspension
The rear suspension uses a linkage-mounted monoshock configuration with automatic electronic preload control. Compression and rebound damping adjustments are manually adjustable, allowing the rear suspension to be tuned within the available settings. The monoshock arrangement integrates with the cast aluminum swingarm and chassis structure. Rear wheel movement is managed through the linkage system and suspension assembly. Rear suspension travel matches the front at 6.7 inches.
Braking Systems and Control Technologies
The braking package of the 2026 Harley-Davidson® Pan America® 1250 ST combines large-diameter brake rotors with advanced electronic control systems. Front braking is handled by radially mounted monoblock four-piston calipers operating on dual floating rotors. The rear brake uses a floating single-piston caliper paired with a solid uniform-expansion rotor. This combination creates a complete braking system designed around both mechanical and electronic components. Anti-lock Braking System functionality is included as standard equipment.
Brake Components
The front brake rotors measure 320 mm in diameter and 4.5 mm in thickness. The dual-rotor arrangement provides braking hardware at both sides of the front wheel. At the rear, the rotor measures 280 mm in diameter with a thickness of 5 mm. The front rotors are floating and hub-mounted, while the rear rotor uses a solid, uniform-expansion design. These specifications define the physical brake components used throughout the motorcycle.
