The belly pan doesn't help with heat that I've noticed. I can't say that it makes any heat issues either. But it's something that I wouldn't want to run without.

I just added some Baker hand wings at Xmas. I really liked them with the cold weather riding. They really blocked off a great deal of the wind to my hands.

Yesterday I took a ride and temps were around 90. At first I forgot the wings were still closed but there was a good bit of heat coming up off the radiators. Not unbearable but annoying. Then I flipped them open and it helped. I'm considering removing them for warmer temps.

I didn't have any issue with wind blast or buffeting but I did prefer the air flow without them. And I am running a mad5stad as well
