Description
The stock reed valve in your YZ125 is limiting your engine’s breathing potential, costing you measurable power across the entire RPM range. Boyesen’s dual-stage reed design has been proven through laboratory flow analysis to deliver superior performance from cold start through peak acceleration. If you’re serious about extracting every available horsepower from your two-stroke, upgrading to a high-flow reed is one of the most direct bolt-on improvements you can make.
