OP, I don't know why you crashed, but to prevent road rash while wearing jeans you ever think of wearing protective shorts like Forcefield?
I was familiar with the entry, but the left kink did come up as a little surprise I guess because it's not the noticeable a transition in a cage. I was on constant throttle through the sweeper, but I let off slightly while prepping for the left transition and maybe wasn't smooth enough with the handle bars and change in body position. I wasn't braking at all. All I remember is going from right lean to upright, about to lean left but slapped the ground instead!
