Deep in the world of performance, tuning, and data‑driven riding. We have a 2025 Gen 2 Harley-Davidson Road Glide ST strapped down on our Dynojet 250i dyno.
Our Power Vision Tunes are born from this methodical environment, with transient, sweep and load control testing delivering all the data and information we need to produce an uncomprimised, complete tune. This isn’t a quick “run it up and see what it makes” setup. It’s a controlled space where we can chase torque curves, map throttle response, diagnose fueling, while seeing the machine’s heartbeat translated into graphs and gauges.
This 2025 Harley‑Davidson Road Glide ST CVO is equipped with a brutal setup:
- SE 135ci Engine
- CycleRama 557 Cam
- 70mm Throttle Body
- 8.7 Injectors
- Burns HnB 2‑1 Exhaust
- Dynojet Power Vision
This combination already has huge potential — our job was to unlock every bit of it safely, smoothly, and with precision.
The end result:
🔥 Power & Torque Characteristics
• Max Power: 171.52 hp at 6,179 rpm
• Max Torque: 174.24 ft‑lbs at 4,149 rpm
That torque figure is enormous for a V‑twin, and the fact it peaks just over 4k rpm tells you exactly how this engine behaves on the road: massive mid‑range shove. This is the most powerful Harley we have had the pleasure to work on.
The peak numbers do not tell the full story. Every throttle opening is taken care of, with smoothness and ridabiltiy an absolute priority. Attention to decel and engine braking is taken care of. This bike delivers, no matter the speed or style of riding.
🏍️ What This Means in the Real World
This bike will feel effortless in the midrange. Roll‑on acceleration will be addictive. You won’t need to wring it out to feel the power—it’s all right where you actually ride.
Paired with the complete dyno setup, we are building a machine that behaves beautifully on the road.
