Description
Reed valve performance directly impacts your YZ125’s throttle response and overall engine efficiency across the entire RPM range. Boyesen’s dual-stage reed design has been laboratory-validated to outflow standard reeds, delivering measurable gains in flow velocity under varying operating pressures. If you’re serious about maximizing acceleration and mid-range pull, upgrading to proven racing reeds is one of the highest-ROI modifications you can make.
