Harley-Davidson CVO Road Glide ST Review (2026): 121 HO V-Twin, Track Modes & Dyno Test
The 2026 Harley-Davidson CVO Road Glide ST is the factory-built performance bagger derived directly from King of the Baggers road racing. Powered by the Screamin' Eagle Milwaukee-Eight 121 High Output V-twin, it produces 127 horsepower at 4,900 RPM and 145 lb-ft (197 Nm) of torque at 4,000 RPM. A high-performance camshaft, Screamin' Eagle heavy breather intake, and lightweight titanium mufflers with forged carbon fiber end caps raise the rev limit to 5,900 RPM. Forged carbon composite components across the front fender and seat cowl shed 25 pounds compared to standard touring models. Fully adjustable 47mm inverted Showa forks, remote-reservoir rear shocks, Brembo radial calipers, and a 12.3-inch Skyline OS touchscreen display anchor this flagship machine at an MSRP of $44,999 USD.
The Strengths
- Milwaukee-Eight 121 High Output V-twin delivers 145 lb-ft of torque, surging ahead with instant roll-on acceleration in all six gears
- Race-spec Showa 47mm inverted forks and remote-reservoir shocks offer full damping adjustability and superior cornering clearance
- Brembo radial-mount monobloc calipers clamped to dual 320mm wave rotors supply massive braking bite with precise two-finger control
- Forged carbon fiber front fender, tank console, and seat cowl drop weight by 25 pounds compared to conventional CVO models
- Vast 12.3-inch color TFT touchscreen running Skyline OS provides crisp anti-reflective navigation, vehicle diagnostics, and audio controls
- Dedicated Track and Track Plus ride modes optimize throttle response, disable rear wheel lift mitigation, and loosen traction control
The Compromises
- Premium $44,999 base MSRP puts this machine into elite exotic touring territory
- Aggressive solo performance seat and omission of passenger footpegs require costly factory accessory additions for two-up touring
- Tipping the scales at 363 kg (800 lbs), low-speed garage maneuvering demands muscular physical effort on uneven surfaces

Technical Deep Dive: Racing DNA in an 800-Pound Super Cruiser
1. Milwaukee-Eight 121 High Output Architecture
The heart of the CVO Road Glide ST is the 1,977cc Milwaukee-Eight 121 High Output powerplant. Unlike standard touring V-twins that focus purely on low-RPM chug, this engine incorporates a high-performance camshaft with extended duration, an oversized throttle body, and a Screamin' Eagle heavy breather air cleaner. Cylinder heads feature CNC-ported intake ports and liquid-cooled exhaust valves that prevent detonation under prolonged track loads. This combination pushes peak output to 127 horsepower at 4,900 RPM while maintaining a towering 145 lb-ft of torque at 4,000 RPM. Titanium mufflers with forged carbon end caps shed exhaust weight while producing a deep, authoritative exhaust cadence that remains legal under federal noise limits.
2. King of the Baggers Chassis Geometry and Showa Dynamics
To tackle aggressive lean angles on winding mountain roads and track circuits, Harley-Davidson raised the ride height on the ST platform. The 47mm inverted Showa cartridge forks offer 117mm of travel with adjustable rebound and compression damping on each fork cap. In the rear, dual Showa emulsion shocks with piggyback remote reservoirs increase travel to 76mm, providing superior bump absorption and a 3-degree increase in cornering lean angle over standard Road Glides. Stiffened motor mounts and beefed-up swingarm bearings eliminate chassis flex when accelerating out of tight corners under full torque.
3. Skyline OS Infotainment and Track Electronics
Dominating the cockpit is a 12.3-inch landscape TFT display that replaces all traditional analog dials. Running Harley-Davidson's Skyline OS, the unit offers customizable display themes, embedded worldwide satellite navigation, and Bluetooth connectivity for smartphone audio streaming. The fairing houses a Rockford Fosgate Stage II 500-watt audio amplifier connected to fairing-mounted speakers designed to project crisp sound at 80 mph highway speeds. Furthermore, the ST features dedicated Track and Track Plus ride modes that decrease traction control intervention, deactivate rear wheel lift mitigation, and sharpen throttle response for track days.
4. Comparative Context and Long-Distance Usability
When compared against megabikes like the Triumph Rocket 3 Storm R or crossover missiles like the BMW M 1000 XR, the CVO Road Glide ST delivers a distinctively American touring experience. The frame-mounted sharknose fairing cuts through highway turbulence with minimal helmet buffeting, and the standard weatherproof hard saddlebags accommodate gear for multi-day tours.
