So what's your comfort range?
The hottest temps I've ridden in was over 115 going thru Wendover, UT in the summer of 1998. That was part of a 3 week/6000 mile trip that included visiting the Grand Canyon, the BMW MOA Rally in Missoula MT and the Top O' The Rockies Rally in Paonia, CO. Luckily it was a dry heat

.
The coldest was 22 degrees riding to Dallas (100 miles from my place) for a bike show, no heated gear. I was hugging the engine during that ride. Both these trips was on a BMW K75.
This last summer in Texas was the worst for riding. Several days of 100+ temps took the joy out of getting on a motorcycle for me. It was hot even with mesh gear. I left my helmet faceshield closed, otherwise it was like riding into a blow dryer set on high.
For me the perfect riding temps range from the high 50's to the high 70's. East Texas does get some beautiful riding weather, even in the dead of winter. Last Saturday it got up to 77 with clear skies. But I had to work that day and wasn't able to take advantage of the riding

. Did get in a short ride on Sunday, nothing intense just a sport-cruise, it was 68 and beautiful.
