FWIW, the ST is a pizza oven on two wheels, but as mentioned before, good boots, riding pants and even the socks make a difference. I rode once this summer in blue jeans and hated it. I thought it was much hotter than wearing the riding pants. I have Joe Rocket Alter Ego pants (just ordered the JR Phoenix 3.0 mesh), TourMaster Solution boots, Rev-It and Alpine Stars Summer socks.
I find the sweating helps melt off my buttermilk in the summer. Just stay hydrated!
