Description
Stock water pumps can’t keep pace with the demands of high-RPM racing, leaving your YZ125 vulnerable to thermal stress and performance loss. The BOYESEN Impeller Water Pump Cover delivers measurably higher coolant flow across the entire RPM band, keeping your engine operating within its optimal thermal window. With a patented Nautilus-style impeller geometry engineered for hydrodynamic efficiency, this is a straightforward bolt-on upgrade that translates directly to better cooling performance and engine longevity.
