This being my first Harley (2015 RGU CVO) I don't have the knowledge of what it used to feel like. But I can tell you to me it isn't the head temperature that gets to me. It is the heat from the catalytic convertor that is the problem. Even my wife has mentioned it while we are our riding. She has had to move her right foot off the boards and put it up in my lap to get her foot to cool off from the heat being generated by the catalytic convertor. I also feel the heat in my right boot while out riding along at cruising speed. Thank goodness I have the highway pegs to move my feet forward and get them away from that heat on the right side.
