When moving the air keeps the heat away from you, I wonder if the ones who complain about the heat have any kind of fairing or wind deflectors?.
tbh I think a couple of things impact the heat sensation (apart from the pipes).
Does cool air help - yes. I have air deflectors pushing air towards the engine for this reason.
I think a large screen maybe lifts heat more to the upper leg through turbulence - but that may just be a general perception of no direct wind.
But foot/leg position depending on physical build and rest position. And riding style.
Boot height and or pants leg materials.
Two sorts of heat - airflow will not eliminate burns (extreme case) from radiation. Been there - just once - wear longer socks.
Ambient heat. If you're riding in 50°C (or even 40) the air chill effect is lessened quite dramatically.
Pipes look good and no doubt will work well (esp on a matched motor) - but I'll pretty much guaranty MY knee would hit that rear header if fitted to MY R3 as it is comfy for ME to ride - So for me that would affect seriously riding gear choice.
i.e no kilt unless you staple fibreglass to your inside leg. But I know Scots like that sort of thing
- Many actually get exiled for it.
edited - Do those "condoms" come in leg covering sizes I wonder.
