Its structural layout, braking package, and electronic support features reflect a configuration intended for street handling, highway travel, and controlled cornering performance.
The motorcycle measures 88.2 inches in overall length, 35.3 inches in width, and 52.4 inches in height. It uses a 62.2-inch wheelbase, a 25-degree rake angle, and 3.7 inches of trail. These dimensions support stable steering response while maintaining maneuverability during lower-speed operation and directional transitions. Static ground clearance measures 6.7 inches. Fuel capacity is rated at 5.6 gallons, and estimated fuel economy is listed at 46 mpg. The weight as shipped is 511 pounds, while the running order weight is listed at 546 pounds.
Revolution® Max 1250 Engine Configuration
The 2026 Harley-Davidson® Pan America® 1250 ST uses the Revolution® Max 1250 engine. This liquid-cooled V-twin powerplant displaces 1,252 cc, or 76.4 cubic inches. Bore measures 4.134 inches, and stroke measures 2.846 inches. The compression ratio is rated at 13.0:1. The engine uses chain-driven dual overhead camshafts with hydraulic self-adjusting lifters and variable valve timing on both intake and exhaust valves. Four valves are used per cylinder.
Electronic Sequential Port Fuel Injection manages fuel delivery. The intake system uses a downdraft intake layout with tuned velocity stacks and washable filter media. Exhaust routing follows a 2-into-1-into-1 configuration with the catalyst integrated into the header assembly. Lubrication is managed through a semi-dry sump system.
Output figures are rated at 150 horsepower at 8,750 rpm and 94 ft-lb of torque at 6,750 rpm. These specifications support broad acceleration capability across multiple rpm ranges. The engine torque testing method follows J1349 standards. Harley-Davidson® recommends 91-octane or higher fuel for operation.
Six-Speed Transmission and Final Drive Setup
The drivetrain uses a 6-speed transmission paired with a mechanical assist-and-slip clutch. The clutch uses an 8-plate wet design with a 1090N specification. This configuration supports smoother downshifts and reduced clutch lever effort during operation.
Primary drive uses a gear-driven 49/89 ratio system. Final drive uses a chain setup with a 19/48 ratio. Overall gearing ratios are listed at 13.11 in first gear, 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. This gearing structure supports both lower-speed response and higher-speed cruising efficiency.
Chassis Structure and Frame Design
The 2026 Harley-Davidson® Pan America® 1250 ST uses a stressed-member frame constructed from high-strength low-alloy steel. The trellis frame integrates stamped, cast, and forged junction sections joined through MIG welding techniques. An aluminum forged mid-structure is incorporated into the chassis assembly. This structural design reduces excess frame material while maintaining rigidity and load distribution characteristics.
The rear section uses a one-piece cast aluminum swingarm. Combined with the overall chassis geometry, the frame configuration contributes to controlled handling characteristics and balanced weight distribution. Gross Vehicle Weight Rating is listed at 1,003 pounds. Gross axle weight ratings are 399 pounds at the front and 665 pounds at the rear.
Electronically Managed Suspension Components
Front suspension uses a 47 mm inverted fork system with electronically adjustable preload. Compression and rebound damping are manually adjustable. Aluminum fork triple clamps are integrated into the assembly. Rear suspension uses a linkage-mounted monoshock with automatic electronic preload control and manually adjustable compression and rebound damping settings.
Front and rear suspension travel both measure 6.7 inches. The suspension package supports street-oriented handling while maintaining controlled wheel movement during cornering and braking transitions. The motorcycle also offers optional Adaptive Ride Height suspension compatibility. With the optional system installed, laden seat height in the low position measures 29.4 inches, while unladen low seat height measures 31.7 inches.
Sport-Focused Wheel and Tire Package
The 2026 Harley-Davidson® Pan America® 1250 ST uses cast aluminum wheels finished in satin black. The front wheel diameter measures 17 inches with a width of 3.5 inches. The rear wheel diameter also measures 17 inches, with a width of 5.5 inches.
Michelin® Scorcher Sport tires are fitted as standard equipment. Front tire specification is 120/70ZR17 58W. Rear tire specification is 180/55ZR17 73W. The tire sizing and wheel dimensions support road-focused grip characteristics and cornering stability during paved-road operation.
Lean angle measurements are rated at 37 degrees on both the left and right sides. Lean angle testing follows J1168 standards.
High-Performance Braking Systems
The braking system uses dual floating front rotors with radially mounted monoblock 4-piston calipers. The front rotor diameter measures 12.6 inches with a thickness of 0.17 inches. Rear braking uses a solid, uniform expansion rotor paired with a floating single-piston caliper. Rear rotor diameter measures 11 inches with a thickness of 0.2 inches.
An anti-lock braking system is included as standard equipment. Electronic Linked Braking is also included. These systems assist braking stability and brake force distribution during changing riding conditions.
The motorcycle also incorporates cornering-enhanced braking systems. Cornering Enhanced Anti-lock Braking System and Cornering Enhanced Electronic Linked Braking are designed to support brake management while the motorcycle is leaned into a turn. These systems use vehicle dynamics data to adjust intervention thresholds during operation.
Integrated Rider Assistance Technology
The 2026 Harley-Davidson® Pan America® 1250 ST includes multiple electronic rider assistance systems. Standard systems include the Traction Control System, the Drag-torque Slip Control System, the Vehicle Hold Control, the Tire Pressure Monitoring System, and the Wheel Lift Mitigation.
Cornering-specific systems are also integrated into the motorcycle. These include Cornering Enhanced Traction Control System and Cornering Drag-torque Slip Control System. Enhanced Lift Mitigation is also included. These systems use lean angle and chassis data to manage acceleration, traction behavior, and wheel control during cornering transitions.
Vehicle Hold Control assists during uphill starts by maintaining temporary brake pressure after the rider stops. The Tire Pressure Monitoring System provides pressure information through the display interface. Drag-torque Slip Control assists rear-wheel management during aggressive deceleration and downshifting events.
