Water Pump Impellers
MCE Racing is currently developing a water pump impeller designed by a hydrodynamic specialist to eliminate cavitation in the water pump housing. Until this impeller is in mass production, MCE can offer a modification to your existing impeller that will yield a modest improvement in cooling. Honda RS125s generally experience an improvement of 2 to 3 degrees Celsius.
