The most powerful Milwaukee-Eight® engine ever factory-installed in a Harley-Davidson® motorcycle. The same V-twin block used in the H-D Factory Race Team Road Glides, this Stage IV powerhouse features CNC-ported heads, Screamin’ Eagle internals, and a SE8-550 camshaft—cranking out 153 horsepower and 150 ft-lb of torque while revving to 6,500 RPM.
Designed and built to withstand race-speed punishment while delivering enhanced gear engagement and durability. Shot-peened gears and shafts increase strength, while back-cut shift dogs keep every shift locked in under race conditions.
The race-inspired intake system features a massive 68mm throttle body for increased power and smoother airflow. A CNC-machined aluminum intake manifold minimizes weight, while the washable Screamin’ Eagle® High Flow air filter delivers a deep, aggressive intake sound.
Fully adjustable, race-spec Öhlins suspension raises ride height by 2 inches, increasing lean angles for aggressive cornering. The 43mm Öhlins FGR inverted forks in the front, coupled with dual Screamin’ Eagle® Öhlins Remote Reservoir shocks in the back, provide razor-sharp handling and precise feel.
Developed by Harley-Davidson Factory Racing, this billet aluminum swingarm is engineered for precision handling, reduced unsprung weight, and improved suspension response. Machined from a 220-pound block of 6061 aluminum down to just 18 pounds, it’s race engineering at its finest.
Nickel plated GP4-RX CNC calipers, with four 32mm pistons, deliver MotoGP-grade stopping power, while 320mm Brembo™ T-Drive front rotors maximize braking efficiency under extreme conditions.
Track Mode, developed with Harley-Davidson Factory Racing rider Kyle Wyman, fine-tunes throttle response, braking, and traction control for maximum performance and feel on a closed-course racetrack. Track Plus Mode pushes further, dialing back rider aids for advanced riders who want full control with minimal intervention from electronic aids. These are just two of nine selectable ride modes—each available at the press of a button—that allow riders to fine-tune power delivery, engine braking, ABS, traction control, and more.
The most advanced display ever offered on a Harley-Davidson® motorcyle, powered by Skyline™ OS. The massive 12.3-inch touchscreen delivers a bright, intuitive interface. Wireless Apple CarPlay®, Bluetooth®, and embedded navigation keep you connected, while over-the-air updates ensure your system is always up to date.
The Rockford Fosgate® Stage III audio system pumps out 500 watts of powerful, high-output sound through 6.5 inch, 3-way fairing speakers—engineered to perform at speed. As an official partner of Harley-Davidson Factory Racing, Rockford Fosgate® delivers the same power and precision to audio that H-D brings to the track.
