Really it’s just about radiant heat and how you’re positioned. When I’m Hooning and playing I don’t even registerthe temps, my minds too busy to notice that inconsequential crap.
When I’m cruising at 30-40 mph, on a hot day, I can feel it but it’s tollerable. Once upon the freeway I can’t feel it anymore at all, even in almost 90f ambient temps.
You’re going to feel some heat no matter what you do at times, how much and how hot will be determined by leg position, tune, and heat shields.
