Maybe you should look at the post by @BGetz about his uncle's crash?Speaking of ATGATT, I must admit that since trading in my Goldwing for my RT, my riding attire has loosened up significantly. Recently I rode wearing shorts, a t-shirt and sneakers, plus an open face helmet, and it was really nice. No jacket, no gloves, not even jeans. Right or wrong, I feel that on the Spyder the chances of me ending up on the pavement are very, very low. As a former MSF Instructor I do feel a tad guilty riding like that, but I still do it for the comfort.
You might rethink things.
Humidity gets to me, makes it hard to breath.
Years ago I was at some desert races in July and was ok.
To be honest though, I not sure how I would do now.
