BOYESEN Water Pump – Case + Impeller Kit (ref. WPK-44CL)

Specifically designed for motocross use, this Boyesen kit includes a blue anodized aluminum water pump case and an optimized impeller. Its racing aesthetic gives a competition look to the engine bottom while replacing the original case.

• Kit contents: water pump case + impeller, mounting screws.
• Material: anodized aluminum (blue color).
• Usage: intended for off-road / motocross machines.

The geometry of the impeller and the design of the case are engineered to enhance the flow of coolant compared to the original case, thus contributing to more efficient heat dissipation under intensive conditions. Designed for easy replacement, the kit installs with the provided screws for a clean and secure fit.

Aesthetic and functional, this case adds a racing finish to enduro and motocross sessions while remaining compact and lightweight thanks to the aluminum.
