Key Features of the 2025 Harley-Davidson® CVO™ Road Glide® ST

Milwaukee-Eight® 121 HO Engine

The heart of this machine is the Milwaukee-Eight® 121 HO Engine, the most powerful engine ever in a Harley-Davidson® production motorcycle. With its high-performance camshaft, Heavy Breather Intake, and a raised rev limit, the engine thrives across the tach—punching hard off the line and pulling with authority as speeds build. Throttle response is immediate yet controllable, with fueling that feels crisp and predictable when transitioning from steady-state cruising to quick overtakes. The result is a powerband that rewards riders who like to stay in the meat of the torque while still enjoying top-end pull. Paired with lightweight, free-flowing titanium mufflers, the engine breathes more efficiently for stronger acceleration and a deep, muscular exhaust note that sounds refined rather than raw. Performance Red accents highlight the powerplant’s presence, reinforcing that this is a halo-spec V-Twin built for serious riders.

SHOWA® 47mm Inverted Forks

Front-end composure comes from fully adjustable SHOWA® 47mm inverted forks offering precise control over compression, rebound, and preload. The rigidity of the fork assembly, combined with premium internal valving, translates to tactile feedback at the bars and a planted, settled feel mid-corner. With an adjustment range to match rider weight, luggage load, and riding style, you can set the front end to glide over rough patches on long tours or firm it up for sharper inputs during aggressive cornering. The additional travel improves bump compliance and contact patch stability under braking—helped further by dual floating rotors that resist fade and sustain lever feel. Whether you are braking hard into a decreasing-radius corner or clipping small imperfections on city streets, the front suspension keeps the chassis composed and communicative.

Dual Outboard SHOWA® Remote Reservoir Shocks

Positioned between the saddlebags and rear fender, the dual outboard SHOWA® Remote Reservoir shocks are tuned to provide consistent damping under demanding conditions. By separating oil and gas, the shocks help reduce cavitation and heat fade during sustained spirited riding. The result is a rear end that tracks true under power, resists wallow in high-speed sweepers, and maintains comfort over expansion joints and rough pavement. The shocks’ adjustability makes it easy to set sag correctly and tailor rebound to your preferred pace, ensuring that front and rear suspension feel synchronized. Riders who value a chassis that stays put under acceleration and remains predictably neutral during quick direction changes will appreciate the depth of control available here.

12.3-Inch TFT Display + Skyline™ OS

The cockpit centers on a 12.3-Inch TFT display running Skyline™ OS, a bright, glove-friendly interface that consolidates critical ride data and entertainment controls. Clear, modern gauges give you at-a-glance confidence, while integrated navigation adds traffic and weather overlays to help you select optimal routes. Rockford Fosgate Stage II audio ties into the system for rich, full-bodied sound that cuts through wind at highway speeds. Menus for Ride Modes, Rider Safety Enhancements, and audio are intuitive, minimizing time spent searching through screens. The result is an infotainment hub that feels natural to use from day one, supporting the ride rather than distracting from it. Connect your device, dial in your preferences, and enjoy a cockpit that elevates focus and flow.

Ride Modes including Track and Track +

Eight available ride modes let you shape the motorcycle’s personality to your environment and intent. From rain-friendly settings to daily street calibration, the mapping adjusts throttle response, engine braking, and intervention levels for Cornering ABS and Traction Control. Track and Track + modes unlock performance envelopes reserved for closed-course use—providing heightened responsiveness and reduced intervention for experienced riders in controlled settings. The benefit is consistency. The bike reacts the same way each time you approach a corner or roll on the throttle, so you can build muscle memory and confidence. Combine the mode logic with the bike’s lightweight components—like forged carbon fiber front fender and cast aluminum wheels—and the platform feels lighter, quicker to settle, and more precise at speed.
