The Boyesen kit is top quality and well designed. The housing has an angle that helps keeping the coolant hose spaced from my aftermarket header. Perfect.

Good grief I love this thing. No more emptying the coolant to change the oil. My bike has actually quit overheating which seems to be an issue on the RMZ250.

Hey my water pump seals are bad on my 2017 ktm 350 sxf and I was going to upgrade this to my bike. I was wondering if I was gonna have to buy new seals. Thank you.
No seals are included with these Boyesen Supercooler Water Pump Kits. You can re-use the OEM water pump seal, assuming it's in good condition. Otherwise, check out the Vertex-Winderosa Mechanical Water Pump Seal on our website to order the appropriate kit to fit your machine so you have everything you need on hand to refresh the water pump assembly.
