There is no denying that a colored hose kit can boost the bling factor of a bike, yet they do more than just look good. Silicon hoses have unique properties that are typically superior to stock rubber hoses. For starters, they have a higher temperature rating, higher burst pressure, and are more abrasion resistance than O.E.M. hoses. What makes CV4’s Radiator Silicone Hose Kit different than other silicone hoses is that, for certain models, they offer a Y-Kit, pictured above. The Y-Kit name is referring to how the hoses meet each other. Most stock hose routing has T-junctions where the hoses meet perpendicularly. But the Y hoses meet at acute angles and which increase flow and reduce the amount of turbulence in the hoses.
