  • 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

    Bentley in SC

    Fit on DRZ400s with Acerbis tank

    I put these on my drz400 and they work well. BUT, I did have to cut about 5mm off the top edge on the left side to accommodate my Acerbis gas tank. The S model guards do not connect on the back of the radiators which makes them easier to fit but are not as strong as others.

  • 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.

  • KTM Radiator Fan Kit

    Tim in MT

    Looks nice...can't use

    Parts look to be very nice. But, it WILL NOT FIT with an oversized fuel tank. I have an IMS tank and no matter what i tried it will not fit. So, thought i would save the headache for someone else.

  • CV4 High Pressure Radiator Cap

    Brad in MT

    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!
