The 2025 CVO Road Glide RR is Harley-Davidson’s limited, higher-output, lighter, race-influenced alternative to the CVO Road Glide ST. The current ST is a 2026 model; its published U.S. starting price is $44,999+, while the available manufacturer information does not establish a comparable RR price or whether any RR inventory remains. The specifications below are Harley-Davidson claims, not independent test results.
Because the ST changed model years, this comparison identifies 2025 ST details separately from 2026 ST details where they differ. Sources: Harley-Davidson’s 2025 CVO Road Glide RR, 2025 CVO Road Glide ST, and 2026 CVO Road Glide ST U.S. product pages.

Comparable new-bike price and current availability are not established. | 2025 model; price not stated on the cited specification summary. | Current model page lists a U.S. starting price of $44,999+. |
All figures in the table are Harley-Davidson’s published U.S. specifications for the named model year. They are not independent measurements; the fuel-economy figures are manufacturer estimates.
1. Model year and production status
The CVO Road Glide RR is a 2025 model, and Harley-Davidson says it is “Limited to just 131.” That is the manufacturer’s stated production limit, not an independently audited count. The current CVO Road Glide ST page is for 2026, and Harley-Davidson also published 2025 ST specifications. This is therefore a comparison of a limited 2025 RR with the 2025 and current 2026 ST—not two current, routinely available model-year offerings.

2. Engine size and type
The RR uses a 131-cubic-inch Screamin’ Eagle 131 engine. Both the 2025 and 2026 ST use the 121-cubic-inch Milwaukee-Eight 121 High Output. The larger RR engine is one part of a broader performance-oriented package; displacement alone does not describe how either bike performs in real-world riding.
3. Published horsepower and torque
Harley-Davidson lists the 2025 RR at 153 hp at 5,750 rpm and 150 lb-ft of torque at 4,750 rpm. It lists both ST model years at 127 hp at 4,900 rpm and 145 lb-ft at 4,000 rpm. These are manufacturer figures, not results from an independent, directly comparable test.
4. Running-order weight
Harley-Davidson lists the RR at 785 lb in running order and the 2025 and 2026 ST at 838 lb. The stated difference is 53 lb. Treat these as the manufacturer’s listed weights, rather than measurements made under a shared independent test protocol.

5. Suspension hardware
RR
The RR has a fully adjustable Screamin’ Eagle by Öhlins front fork and remote-reservoir rear shocks, according to Harley-Davidson’s 2025 page.

ST
The ST has adjustable front and rear suspension, but it is not the RR’s listed Öhlins setup. Component details should be tied to the model year: see Harley-Davidson’s 2025 ST and 2026 ST specifications. A parts comparison should not assume the two model lines share identical suspension hardware.
6. Brakes
Harley-Davidson describes the RR’s front setup as Brembo Racing fully floating T-drive rotors and names GP4-RX CNC front calipers with 320 mm front rotors. The ST uses a different specification; the available details do not establish that it shares this exact RR arrangement. The distinction is in the named hardware, not a claim about comparative stopping distances.

7. Exhaust and materials
RR
The RR has an Akrapovič full titanium 2-into-1 exhaust with carbon-fiber heat shields. Harley-Davidson also lists carbon-fiber bodywork and billet-aluminum parts.
ST
The 2025 ST has a 2-into-1-into-2 dual exhaust with titanium mufflers and carbon-fiber end caps, plus a forged-carbon-fiber front fender. The 2026 ST page lists tapered mufflers. These are year-specific descriptions; they should not be collapsed into a single claim about every ST.

8. Published lean angle
Harley-Davidson lists the RR at 37° right and 36° left, compared with 32° on each side for the 2025 ST and 31° on each side for the 2026 ST. These are published specifications; they do not by themselves establish how either motorcycle will feel or behave in a rider’s hands.

9. Seat height and dimensions
The RR’s laden seat height is listed at 28.5 in., compared with 26.7 in. for the ST. The RR also has a listed 64.4-in. wheelbase and 6.3-in. ground clearance; the ST is listed at 64 in. and 5.1 in., respectively. The higher laden seat figure may matter to riders comparing the published fit dimensions, but it does not establish comfort for a particular rider.

Display and ride modes
Harley-Davidson lists a 12.3-inch Skyline OS display for the RR and both ST model years. The RR page describes nine ride modes, including Track and Track Plus. Feature details should be checked on the page for the specific ST year; a feature not mentioned in a summary is not proof that it is absent.
Audio
The RR page specifies a 500-watt Rockford Fosgate Stage III audio system. The cited comparison does not establish a directly equivalent ST audio specification, so it would be misleading to infer that the ST has the same system or none at all.

Price and availability
Harley-Davidson lists the 2026 ST at a U.S. starting price of $44,999+. That figure is for the 2026 U.S. model page. The available information does not establish a comparable RR new-bike price, current RR inventory, or a representative used-market price. A dealer asking price would need to be assessed as a dated, location-specific listing rather than treated as a general RR price.
Which one makes more sense?
The RR is the more specialized choice on paper: its manufacturer-listed output, lower running-order weight, Öhlins and Brembo Racing components, titanium Akrapovič exhaust, and limited production point toward a scarce, track-influenced factory configuration. The ST remains Harley-Davidson’s current CVO Road Glide offering, with its own performance-focused 121 High Output specification and a published 2026 U.S. starting price.
Those specifications do not settle real-world comfort, handling, reliability, maintenance expense, or value. No independent side-by-side test results establish those outcomes here. For an actual purchase, verify model year, equipment, condition, and price on the specific motorcycle or current dealer listing—especially for the limited 2025 RR.
