Boyesen Supercooler Water Pump Cover and Impeller Kit
Shadd in CA
Must have add on for 450's
Great add on to my 450 for when i do trail rides. Have not had an overheat yet. I paired this with a tusk high pressure rad cap and have had no issues. The fit was right on and install was a breeze. Came with the gasket which is always a plus. The only issue i ran into was how close my WC skid plate was too the cooler once installed. It was pretty much touching on the cooler cover and one of the cooler screws. Easy fix was to take some heat to my skid plate and use some big plyers to bend it out a little. 5 stars because you are getting peak performance and 5 star looks.

DeVol Radiator Guards
Paul in VA
Excellent radiator guards
Installed on DRZ400S. Perfect fit, easy install. They seem very sturdy. The left-side guard rubs right up against the housing for the oil tube. I don't think it'll be a problem; I hope it's not a problem

CV4 Radiator Hose Kit
Tim in MT
Fit great
Installed on my 2004 KTM 450exc. Fit excellent. I did trim one hose down so it didn't rub on the frame but that's because my left radiator is slightly bent. So not the hoses fault but was easy to trim is why i included this.

My radiator cap works now!
Works just like a radiator cap should work. Maintains pressure, keeps coolant on the inside. What more could you ask for!
