I have a Scrambler and live in the desert in New Mexico. I commute almost everyday on the bike. It's about 30 miles with a lot of stop and go in the city with temps. up in the 90's - 100. The bike handles it just fine. Myself on the other hand, I have a natural built in evaporative cooler or maybe it's just sweat.

Keep yourself hydrated and it will be fine. The bike can probably take the heat better than we can.
