I'm sorry, if I was to commute in slow moving traffic every day it would probably be annoying, but I did 5 hours recently in 35/39 c . on highway & didn't notice it. ( but I had jeans & boots on). I did notice it when I first bought bike, but has become a non issue.We rode a couple of hiway hours in northern Nova Scotia last year , 33 c and it was unbearable . Must be the humidity up here but 28 or so is as high as I would call comfortable . These new engines make more power , more heat is just a biproduct . Maybe a 400 next time .
Then again our bodies are different, some peoples hot or cold are very different! I hope you can enjoy the bike,
