Put on long pants or the radiator slits (the hot air coming out) will cook the hair on your legs.
^^Most definitely this ^^.
I recommend a cooling vest or, at minimum, a cooling towel to keep your core temp down. Cycle Gear has a vest for about $50 that will cool you for several hours when worn under a jacket. You will also dehydrate quickly because your sweat will evaporate as you ride. Drink twice as much as you think you should, pay attention to your urine output/color (pale good, dark or nonexistent, very bad), and how you feel. If you're even a little "off", you need to stop, drink, and rest somewhere cool.
