Description
Standard reed valves restrict flow across your powerband, leaving performance on the table—especially during critical start-up and mid-range acceleration phases. Boyesen’s dual-stage reed design has been laboratory-validated to outperform conventional reeds by permitting greater flow velocity across the entire operating pressure range. The result is measurable gains in throttle response, peak power delivery, and overall engine efficiency on your YZ125.
