Reinforcement very solid. I installed in a KTM EXC-350.Previously I rode without and unfortunately the radiator on both sides bent during falls. Installation was no problem, especially since I had to replace the radiator with a new one anyway. Here a note - I bought a replacement "Psychic" and it differs in the number of inputs from the OEM - the manufacturer assumes that we want to give up the thermostat right away and there is one less circuit - for me this was a plus. Going back to the "back" - in the right one there is a place to install a fan. I installed an aftermarket one and although the hole is a little smaller, it was possible to fit it in.
