Revolution® Max 1250T Engine Specifications and Output Characteristics
The 2026 Harley-Davidson® Sportster® S is powered by a 1,252 cc Revolution® Max 1250T engine. This engine features a bore of 105 mm and a stroke of 72.3 mm, paired with a 12.0 to 1 compression ratio. The valvetrain consists of dual overhead camshafts with chain-driven operation and hydraulic self-adjusting lifters. Each cylinder uses four valves, and the system incorporates variable valve timing on both intake and exhaust sides. This configuration supports controlled airflow management across the operating range.
The engine produces 121 horsepower at 7,500 rpm and 93 pound-feet of torque at 6,000 rpm. These figures reflect a tuning approach that maintains strong torque output at mid-range engine speeds while continuing to deliver power at higher rpm levels. Fuel delivery is managed by Electronic Sequential Port Fuel Injection. The intake system uses a downdraft design with tuned velocity stacks and a washable filter element, which contributes to consistent airflow and serviceability. The exhaust system is configured as a 2-into-1-into-2 layout with the catalyst located within the muffler assembly. Lubrication is handled through a semi-dry sump system, supporting engine reliability under varied operating conditions.
Transmission, Clutch, and Drive System Configuration
The drivetrain uses a six-speed transmission paired with a mechanical assist and slip clutch. The clutch is an eight-plate wet design, rated at 1090 newtons, which supports controlled engagement and reduces rear wheel disturbance during aggressive downshifting. The primary drive uses a gear configuration with a 49 to 89 ratio. Final drive is handled through a belt system with a 34 to 80 ratio, offering reduced maintenance requirements compared to chain-driven alternatives.
Gear ratios are structured to support progressive acceleration. First gear is set at 12.21, followed by 9.022 in second gear, 6.994 in third gear, 5.641 in fourth gear, 4.731 in fifth gear, and 4.131 in sixth gear. This spread allows the motorcycle to deliver strong initial acceleration while maintaining manageable engine speed during higher-speed cruising. The combination of these ratios with the engine’s torque curve results in consistent power delivery across multiple riding conditions.
Structural Frame and Swingarm Design
The frame is constructed as a stressed-member high-strength low-alloy steel trellis structure. It incorporates stamped, cast, and forged junctions that are MIG welded to ensure structural integrity. The design integrates an aluminum forged mid-structure, which contributes to weight management and rigidity. By using the engine as a structural component, the motorcycle reduces the need for additional frame mass and supports improved handling response.
The swingarm is also built from high-strength low-alloy steel. It uses tubular sections, a stamped cross-member, and forged axle junctions, all joined through MIG welding. This configuration supports stability under acceleration and braking forces. The structural approach is designed to maintain alignment and durability while accommodating the output of the engine.
Suspension Components and Adjustability
The front suspension consists of a 43 mm inverted fork with adjustable compression, rebound, and spring preload. The fork is mounted with aluminum triple clamps, which contribute to front-end rigidity and precise steering input. Rear suspension is handled by a linkage-mounted piggyback monoshock that also provides compression, rebound, and hydraulic spring preload adjustability. This level of adjustability allows the rider to modify suspension behavior to match load conditions and riding preferences.
Suspension travel is measured at 3.6 inches in the front and 3.2 inches in the rear. The relatively short travel distances align with the motorcycle’s low stance and performance orientation. The suspension configuration supports consistent contact between the tires and road surface, contributing to stability during acceleration, braking, and cornering.
Wheel, Tire, and Ground Interface Specifications
The 2026 Harley-Davidson® Sportster® S uses cast aluminum wheels finished in satin black. The front wheel measures 17 inches in diameter with a width of 4.5 inches, while the rear wheel measures 16 inches in diameter with a width of 5 inches. Tire specifications are 160/70R17 for the front and 180/70R16 for the rear, both supplied as Dunlop® Harley-Davidson® Series GT503 radial tires. These tires are designed to provide a balance between grip, durability, and consistent handling characteristics.
Ground clearance is listed at 3.5 inches in static condition. Lean angle capability is measured at 35 degrees on both the left and right sides. These figures indicate a configuration that supports moderate lean angles while maintaining stability. The relationship between tire dimensions, wheel sizing, and suspension geometry contributes to predictable handling behavior.
Braking System and Control Hardware
The braking system includes a radially mounted monoblock four-piston caliper at the front, paired with a single floating rotor measuring 320 mm in diameter. The rotor thickness is 5 mm. The rear braking system uses a floating single-piston caliper with a 260 mm rotor, also with a thickness of 5 mm. The front system is configured as a single-disc setup, relying on the caliper design and rotor size to provide adequate braking force.
Anti-lock Braking System is included as standard equipment. The system is designed to prevent wheel lock during braking, helping maintain steering control. The braking hardware is configured to match the motorcycle’s performance characteristics, providing consistent deceleration under varying conditions.
Electrical System and Instrumentation Interface
The electrical system uses a sealed, maintenance-free absorbed glass mat battery rated at 12 volts and 12 amp-hours, with 225 cold cranking amps at 0 degrees Fahrenheit. Charging is managed by a three-phase 45-amp system, delivering 300 watts at 13 volts at 1,200 rpm and a maximum output of 585 watts at 13 volts at 2,250 rpm. Starting is handled by a 0.9 kilowatt electric starter with direct drive engagement.
