Description
The stock reed valve is your CR250’s bottleneck—restricting airflow and leaving power on the table across the entire RPM range. Boyesen’s dual-stage reed design unlocks measurably higher flow velocity at every operating pressure, translating to sharper throttle response at low RPM and stronger top-end acceleration. If you’re serious about 2-stroke performance, upgrading your reed is one of the highest-ROI modifications available.
