The BOYESEN water pump cover repair kit + impeller (ref. WPK-06DM) is designed for motocross and enduro riders looking for a robust solution for the cooling circuit. Designed for a high-flow hydrodynamic pump, this BOYESEN kit aims to improve the flow of coolant through an optimized impeller, with the goal of achieving a more consistent engine operating temperature during intensive outings.
Made from aluminum and delivered in black, this component replaces the original cover and includes the necessary hardware for installation. Its design takes into account off-road constraints: ease of installation, compact size, and compatibility with motocross/enduro engines.
