Engine and Performance
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 4.134 inches and a stroke of 2.846 inches, creating a configuration designed to support both strong power output and responsive operation across the rpm range. A compression ratio of 13.0:1 contributes to the engine’s performance characteristics while working in conjunction with the advanced combustion and fuel delivery systems. The engine is rated at 150 horsepower, or 112 kW, at 8,750 rpm. Torque output is listed at 94 ft-lb, or 127 Nm, at 6,750 rpm using the J1349 testing methodology.
Advanced Valve Train Design
A key component of the Revolution® Max 1250 engine is its sophisticated valve train architecture. The engine utilizes chain-driven dual overhead camshafts and hydraulic self-adjusting lifters to maintain precise valve operation. Intake and exhaust variable valve timing is integrated into the design, allowing the engine to manage valve events across varying operating conditions. Four valves per cylinder support efficient airflow through the combustion chambers. Together, these systems contribute to the engine’s technical sophistication while maintaining the performance specifications documented for the model.
Fuel Delivery, Intake, and Exhaust Systems
Fuel delivery is managed through Electronic Sequential Port Fuel Injection, commonly referred to as ESPFI. This system provides controlled fuel metering and works in conjunction with a downdraft intake arrangement. The intake system incorporates tuned velocity stacks and washable filter media, creating a carefully engineered airflow path into the engine. Exhaust gases are routed through a 2-into-1-into-1 exhaust system that incorporates a catalyst within the header assembly. Engine lubrication is handled by a semi-dry sump system, while oil capacity with a filter is specified at 4.75 quarts and coolant capacity is listed at 2.32 quarts.
Drivetrain and Transmission
The drivetrain of the 2026 Harley-Davidson® Pan America® 1250 ST is designed to transfer power efficiently from the Revolution® Max engine to the rear wheel. The motorcycle uses a gear-driven primary drive system with a 49/89 ratio. Final drive duties are managed by a chain system utilizing a 19/48 ratio. This arrangement forms the foundation of the motorcycle’s power transmission layout and supports the performance characteristics outlined in the specifications. The drivetrain components are paired with a six-speed transmission that provides a broad range of operating ratios.
Clutch System and Gear Ratios
The clutch is a mechanical eight-plate wet design equipped with assist-and-slip functionality. This configuration is rated at 1090N and forms an important part of the motorcycle’s power management system. The six-speed transmission uses overall gear ratios of 13.11 in first gear, 9.687 in second gear, and 7.509 in third gear. Fourth gear carries a ratio of 6.057, while fifth gear uses a ratio of 5.08 and sixth gear is specified at 4.436. These ratios establish the progression through the gearbox and define how engine output is transmitted across the operating range.
Chassis Architecture and Dimensions
The chassis of the 2026 Harley-Davidson® Pan America® 1250 ST combines steel and aluminum construction techniques to create a rigid structural platform. The motorcycle utilizes a stressed-member high-strength low-alloy steel trellis frame incorporating stamped, cast, and forged junctions. The frame is assembled using MIG welding and includes an aluminum-forged mid-structure. This combination of materials and manufacturing methods contributes to the motorcycle’s overall structural design. Supporting the rear suspension system is a one-piece cast aluminum swingarm.
Geometry and Physical Measurements
The motorcycle measures 88.2 inches in overall length, 35.3 inches in overall width, and 52.4 inches in overall height. Wheelbase measures 62.2 inches, creating the foundation for the motorcycle’s overall proportions. Steering geometry includes a 25-degree rake and a 25-degree fork angle. Trail is specified at 3.7 inches, or 95 mm. These measurements define the motorcycle’s chassis geometry and contribute to its handling characteristics.
Weight Ratings and Operating Capacity
The 2026 Harley-Davidson® Pan America® 1250 ST has an as-shipped weight of 511 pounds and a running-order weight of 546 pounds. The Gross Vehicle Weight Rating is listed at 1,003 pounds. The front Gross Axle Weight Rating is specified at 399 pounds, while the rear Gross Axle Weight Rating is listed at 665 pounds. Fuel capacity measures 5.6 gallons, complemented by a 1-gallon reserve fuel capacity linked to the fuel injection warning system. These specifications provide important information regarding vehicle mass, operating capacity, and fuel storage.
Suspension, Wheels, and Tires
The suspension system combines electronically controlled functions with manually adjustable damping components. At the front, the motorcycle uses a 47 mm inverted fork equipped with electronically adjustable preload. Compression and rebound damping adjustments are performed manually, providing a combination of electronic and mechanical tuning capability. Aluminum fork triple clamps support the front suspension assembly and contribute to the overall chassis structure. This suspension arrangement is designed to work in conjunction with the motorcycle’s frame and wheel package.
Rear Suspension Configuration
Rear suspension duties are handled by a linkage-mounted monoshock. The system incorporates automatic electronic preload control while also providing manually adjustable compression and rebound damping. This arrangement allows the rear suspension to maintain its specified operating characteristics while offering adjustment capability through the integrated system design. The rear suspension works directly with the cast aluminum swingarm to support the motorcycle’s handling and ride dynamics. Front and rear suspension travel are both specified at 6.7 inches.
