Description
Stock reed valves limit your CR125’s potential across the RPM band, forcing you to choose between low-end response and high-RPM power. Boyesen’s dual-stage Power Reed design eliminates that compromise by pairing a lightweight, responsive top reed with a high-flow ported bottom reed, delivering crisp throttle control at partial throttle while unlocking measurable horsepower gains at peak RPM. The included Rev-Plate replaces the restrictive stock reed stop, allowing the reeds to operate at full efficiency without mechanical constraints.
