2021 Supersport 950
I have the same issue sadly. But mostly from 2nd to 3rd. The other gears are fine, but this "being embarrassing as it bounces back in to the lower gear," is really really annoying and happens 6 out of 10 times when I go WOT from 1st gear. Transition to 2nd is fine, and then from 2nd to 3rd I almost kiss my windshield and I look like a fool.I have a similar issue with my 2021 SS. It always struggles shifting up at high revs while accelerating, and apart from it being embarrassing as it bounces back in to the lower gear, it is dangerous if you have someone accelerating quickly behind you.
