BOYESEN WPK-41L — Water Pump Cover + SuperCooler Impeller (blue)
This Boyesen SuperCooler kit includes a water pump cover and a hydrodynamic impeller, developed by the manufacturer to increase coolant flow. Designed for the motocross world, it features a distinctive blue color and a finish designed to withstand track conditions.
The installation replaces the original pump housing and is aimed at riders looking to optimize the cooling circuit of their machine (radiator, pump, and impeller). The kit comes complete with all necessary hardware and a gasket for a clean installation. Manufacturer reference: WPK-41L.
Ideal for motocross and enduro bikes, it is particularly suitable for recent small displacement machines used in competition and leisure (e.g., KTM 150 EXC TPI 2023, Husqvarna TE 150 i 2023, GAS GAS MC 125 2023). For installation, check the specific compatibility with your model and follow the sealing procedure recommended by the manufacturer.
