The 2025 Harley-Davidson CVO Road Glide ST is not a touring bike for retirees. It is a performance bagger born from the King of the Baggers racing series. With the new 121 High Output engine, fully adjustable Showa suspension, and a 28-pound weight reduction, it is the fastest, most aggressive CVO ever built. Here is the complete technical breakdown.

1. Powertrain: Milwaukee-Eight 121 High Output

The heart of the CVO Road Glide ST is the new Milwaukee-Eight 121 High Output V-Twin. This is not the standard 117; it is a performance-tuned monster derived from racing.

Specification CVO Road Glide ST Standard Road Glide
EngineMilwaukee-Eight 121 HOMilwaukee-Eight 117

Final Drive Ratio2.15:1 (shorter for acceleration)2.02:1

2. Weight Reduction: 28 Pounds Lighter

For 2025, Harley-Davidson engineers focused on shedding weight from the CVO Road Glide ST. Every pound saved translates to quicker acceleration and better handling.

  • Total Weight Loss: 28 lbs (12.7 kg) compared to previous CVO models
  • How? Revised chassis components, lighter fairing brackets, and optimized engine mounts
  • Curb Weight: ~850 lbs (386 kg) – still heavy, but lighter than ever for a performance bagger
  • Impact: 0-60 mph times improved by approximately 0.3 seconds

3. Chassis & Suspension

The CVO Road Glide ST is equipped with fully adjustable Showa suspension, a first for a production bagger. This allows riders to dial in settings for aggressive cornering or comfortable cruising.

  • Front Fork: Showa 49mm inverted fork with compression and rebound adjustability
  • Rear Shocks: Showa piggyback reservoir shocks with spring preload adjustability
  • Brakes: Dual 320mm front rotors with 4-piston calipers; rear 300mm rotor
  • Wheels: 19" front / 18" rear with custom CVO finishes
  • Tires: High-performance Michelin Scorcher tires for maximum grip

4. King of the Baggers DNA

The Road Glide ST is not just a styling exercise. Its development was directly influenced by Harley's success in the King of the Baggers racing series, where baggers race on road courses.

  • Racing Heritage: The 121 HO engine shares components with the race bikes, including high-compression pistons and high-lift cams
  • Cornering Clearance: Footpegs and floorboards are designed for higher lean angles than standard tourers
  • Electronics: Cornering ABS and cornering traction control are standard, using IMU data
  • Top Speed: Electronically limited to 120 mph (193 km/h) for 25 seconds, suitable for track use

TECH INSIGHT: The 121 HO Engine

The 121 High Output engine achieves its 127 hp through a combination of increased displacement (121 ci vs 117 ci), higher compression ratio (11.4:1), and a more aggressive camshaft profile. The Screamin' Eagle titanium mufflers reduce backpressure while maintaining a throaty V-Twin rumble. The shorter final drive ratio (2.15:1) means the engine spins faster at any given speed, sacrificing top-end speed for explosive acceleration out of corners—exactly what you need in a race.

5. Dimensions & Capacities

6. Price & Availability

  • MSRP (2025): $44,999
  • Production: Limited (CVO models are always limited production)
  • Colors: Raven Metallic / Redline Red (as shown), plus other CVO exclusive finishes
  • Availability: At Harley-Davidson dealers now (as of mid-2025)

Engineering Verdict: The Bagger That Learned to Fly

The 2025 Harley-Davidson CVO Road Glide ST is proof that baggers can be fast. With 127 hp, 145 lb-ft of torque, and a 28-pound weight reduction, it is a genuine performance machine disguised as a tourer. The fully adjustable Showa suspension, shorter final drive, and King of the Baggers-derived engine make it the most capable cornering Harley ever produced. It is not for everyone—the $45,000 price tag and limited production ensure exclusivity. But for riders who want to carve canyons on an American V-Twin, there is simply no substitute.
