  • CV4 Radiator Hose Kit

    CV4 Radiator Hose Kit

    BRIAN in UT

    Could not be more disappointed

    I needed to replace a hose on my KTM before riding this weekend. Figured I would go ahead and buy this kit and replace everything. First problem is this kit does not contain everything! The description neglects to mention that for KTM bikes with a thermostat, you need to be willing to put the t-stat in the trash. In my case, I have already removed the t-stat but I put in a TrailTech temp sensor in its place. The sensor uses the hoses for the t-stat housing so using the bypass hose is not an option for me. Also, the kit does not come with the hose that ties the upper radiators to the in-frame piping. The hose that HAD to be replaced was the inlet. The hose itself needed to be trimmed (not a big deal) but I had to both trim more than I should have and twist the hose as I tightened the clamps to keep it off the frame. I also looked at removing the temp sensor by using the bypass hose just to feel better about the mistake I made by purchasing this kit but the hose hits the valve cover even after trimming it. In the end what I have is a very expensive, very temporary fix. For such a highly advertised name and product CV4 has completely dissapointed me.

    Sits in front of radiators

    Just like the previous reviewer stated, it's odd that these don't sit around the radiators to protect them. They form a space in front of the radiators and protect that way. I wonder how these will hold up on a side impact. I saw someone selling one side on ebay, because he crashed and trashed the other side. Other than that, they seem to be sturdy and line up fairly well. It took me an hour to put it together. The plastic black protectors up front are tricky to install inside the guards: the first took me 15 minutes to figure it out, while the other side went right in. I left out my bottom shroud bolts because they did not line up and seemed to be superfluous.
