127 horsepower at 4,900 rpm. 145 lb-ft of torque at 4,000 rpm. $44,999 MSRP, plus $875 destination charge for the 2025 model. That makes the CVO Road Glide ST the most powerful production pushrod V-twin Harley-Davidson has ever built, and it’s not close.

This table is the single most useful thing on this page if you’re trying to understand what you’re actually paying for as you move up the Road Glide lineup. The jump from standard Road Glide to CVO buys you displacement and finish. The jump from CVO to CVO ST buys you a genuinely different engine tune, race-derived intake and exhaust, and track-informed suspension.
What’s Different Under the Bodywork
The standard High Output tune skips Variable Valve Timing entirely, a deliberate choice for maximum top-end power and a two-pound weight savings over the VVT-equipped standard 121. This is the same design philosophy Harley’s Factory Race Team uses on the actual King of the Baggers competition bikes that inspired this model.

The Heavy Breather intake and Screamin’ Eagle exhaust components aren’t cosmetic. They’re functional performance parts that genuinely change how the engine breathes under hard acceleration, which is exactly why the rev limit climbs to 5,900 rpm compared to the standard Road Glide’s more conservative redline.
Touring Parts Crossover: Parts That Fit From the Road Glide Family
Here’s the practical question every CVO Road Glide ST owner eventually asks. Since this bike shares its core touring platform, saddlebags, fairing structure, and general chassis architecture with the rest of the Road Glide lineup, meaningful crossover exists for owners looking to source parts today rather than waiting on ST-specific listings.
Saddlebag hardware, general touring electrical components, and certain fairing mounting hardware often follow shared specifications across the Road Glide family, standard, CVO, and ST alike. The engine-specific components, exhaust, intake, and anything tied to the High Output tune, are unique to the ST and won’t cross over from a standard Road Glide or even a non-ST CVO model.
Performance Parts and Wear
Harley built this bike’s reputation on the MotoAmerica King of the Baggers series, and that racing pedigree tells you exactly what to expect for wear patterns if you ride the ST the way it’s designed to be ridden.
Brake components see faster wear under hard, repeated braking, the same braking style that defines bagger racing. If you’re using the ST’s performance rather than just cruising, budget for more frequent pad inspection than a standard touring rider would need.

Suspension components, particularly the remote-reservoir units, benefit from more frequent fluid and seal checks under aggressive use than Harley’s standard touring suspension setup, since these components are tuned for a wider performance range and see more work when ridden hard.
Clutch and drivetrain components under the High Output engine’s increased torque output see more stress than the standard Milwaukee-Eight 117 in daily aggressive use, particularly for riders who explore the elevated 5,900 rpm rev range regularly.
Stocking Up Ahead of the Curve
Aliwheels has the more extensive Road Glide and CVO range of Harley Davidson Parts already covered, so CVO Road Glide ST owners have real, usable options today for shared touring hardware, saddlebags, general electrical components and fairing hardware. As performance parts specific to the High Output become available across the industry, we’re expanding our catalog to include confirmed fitment for this exact engine and chassis combination.
Frequently Asked Questions
What is the Harley-Davidson CVO Road Glide ST price?
US MSRP is $44,999, plus an $875 destination charge for the 2025 model year.
How much horsepower does the CVO Road Glide ST have?
127 horsepower at 4,900 rpm, with 145 lb-ft of torque at 4,000 rpm, the highest output ever from a production Harley-Davidson pushrod V-twin.
What engine does the CVO Road Glide ST use?
The Milwaukee-Eight 121 High Output, a 1977cc pushrod V-twin tuned specifically for this model with a Heavy Breather intake and elevated rev limit.
Do standard Road Glide parts fit the CVO Road Glide ST?
General touring hardware, saddlebags, some fairing mounts, and electrical components often cross over, since the platform shares core architecture. Engine, exhaust, and intake components specific to the High Output tune do not cross over.
What is the difference between the CVO Road Glide and the CVO Road Glide ST?
The standard CVO Road Glide uses the Milwaukee-Eight 121 at 115 hp. The ST uses a High Output version of the same displacement, tuned for 127 hp with a higher rev limit, upgraded intake, and race-derived exhaust.
Is the CVO Road Glide ST hard on parts if ridden aggressively?
Yes. Brakes, suspension seals, and drivetrain components all see faster wear under the kind of hard, repeated riding this bike is actually built for.
