I find that as I age I tolerate the heat a lot less than when I was young(er). I don't like riding in temps much above 80*. My ideal temp range for riding is 55* - 75*. Consequently my annual mileage is much lower these days. My bike goes into storage twice a year, once for the Winter months of Dec.- March, and the second time during the "Dog Days" of Summer which came earlier this year. Gonna have heat index of 105 - 110 for the upcoming weekend.
