Discover the shocking truth behind Harley-Davidson Road Glide CVO ST performance in this eye-opening dyno session at Torque Custom Cycles! Two identical 2024-2025 CVO ST bikes with the powerful 121ci High Output engine received the same Stage 2 upgrades: S&S 857 cam (MaxCell), Trask air intake, Bassani 3/4 exhaust, stock throttle body/injectors, and Impact Solution tuning.
Watch as we compare baseline and tuned dyno pulls side-by-side. One bike delivered impressive 130 hp / 135 ft-lbs after tuning, while the other surprised with higher baseline numbers (up to 134 hp / 141 ft-lbs uncorrected) before settling close post-tune—proving no two engines are identical due to manufacturing tolerances, even with matching parts!
We dive deep into real-world factors like chain vs. belt drive power loss (5-10 hp difference), lean running risks, heat issues, and why these Milwaukee-Eight 121 motors shine with simple Stage 2 mods—no big bore needed for massive torque!
Perfect for CVO owners considering cams, intakes, exhausts, or dyno tunes. See why the CVO Road Glide ST is a torque monster with track mode thrills.
