The Flatland Racing Radiator Guards are a set of aluminum alloy cages that keep your radiators straight and true by supporting them during front and side impacts. Flatland designs the Radiator Guards to handle such abuse by building them from 1/8 inch (3.2 mm) thick aluminum alloy, attaching them directly to your bike's frame, and giving them a rear mounting bracket for additional support. This gives the Flatland Racing Radiator Guards a triangle-like support system that lets the guards soak up abuse without bending, deforming, or passing that damage through to your radiators.
