Anyone else have this issue where you subconsciously squeeze the tank with your legs? I'll be riding along going straight down the freeway and for whatever reason I start clenching my legs against the tank. The rest of my body is loose and comfortable. I have to force myself to loosen up my legs and then 10 or 15 minutes later I notice i'm clenched again. Not sure what this is but it makes for tired legs after 500 miles.
