I was about to post the same. I find that when riding with a lot of steering input, I start to notice my hands being sore from the vibrations. Didn't really pick up on it until this trip at the gap. Previously it was my palms being sore from bar input, now it feels more sore from the vibrations. I'll work on lighter on the bars, but hard when the road is super twisty, requiring a lot of input on the bars. Not like a sweepers or a normal racetrack where there is some time between the corners.
I feel it more on my left hand.
More riding adjustments in my future. I'm trying to work on body position and this may be affecting my hands.
