I agree with most everything you posted.
Context is key here, I use full termi and upmap key. Love my gearing though.
What your explaining while correct, is not OP's issue which is learning a twin.
The bike does 73mph in 1rst gear, and OP is complaining he cannot corner and accelerate to 80 quickly because 4000 rpm she stumbles.
That's driver error.
And yes your correct you need to stay in the powerband on this bike, it is not like the 1098, OP was no where near the powerband.
Maybe I was to hard on the little feller, but after years in ducati forums this same complaint is made by twin noobs constantly.
As you know it just takes some getting used to, and these bikes demand more of the pilot. And they are not road friendly unless your aggressive.
