Description
Stock reed valves restrict flow and limit your YZ250’s potential across the entire RPM range. Boyesen’s dual-stage reed design has been lab-proven to deliver higher flow velocity at all operating pressures, translating to sharper throttle response off the bottom and stronger top-end acceleration. If you’re serious about two-stroke performance, upgrading your reeds is one of the most effective bolt-on modifications available.
