Description
A radiator valve optimizes intake charge distribution across your CR125’s cylinder, eliminating dead zones that rob you of power and throttle response. Boyesen’s dual-stage reed design maintains flow velocity while sharpening how your engine responds to throttle input, translating to measurable horsepower gains throughout the entire RPM range. Installation is straightforward—the one-piece cast aluminum design bolts directly in place without fabrication.
