I had one of the first MT-09 in 2013 in switzerland and like the Tracer 900, to me it's too light for the angry engine and throttle response while fun in the beginings is what causes a lot of issues. On normal roads it's just too extreme and I had many "oh ****" moments squeezing butcheeks !
The guys comment are also right, the front forks are not that great on those cheaper Yamahas, MY 2010 FZ8 had non adjustable but much more quality forks on it, I never felt like it would bounce off the road like the MT !
But where I really don't agree with what you say and what the guys thought, the "trails can't go fast in twisties" is nonsense, some people's driving styles are draging knee on a R6, some others throwing the handlebar on Trails, I'm of the later kind and I can quite easily follow or go faster than sportbikes on normal roads, It's having a bike that compliments your style that does the trick !
Track racing is another thing and of course Trails won't stand a chance of course, but because of high end power.
And Apparently the DCT is good to you, but I'm pretty sure a manual would have done just the same, because if I kinda race like you described I never go to fourth gear and sometimes to stay in middle revs were everything jumps, I don't always drop a gear, I use the clutch and jump out of corners, the DCT can't do that, It's a matter of driving style again.
I couldn't do this on the MT without TC it was too extreme, I tried and got really scared !
I really liked the Yamaha prices, but I think they hardware quality is a bit decreased, that's why I switched boats to Honda, whatever people that are disappointed with the AT quality say, you don't get better at such price.
But what amazes me mostly with the Honda, is I don't need that much concentration or confidence, it's mostly effortless to drive fast in twisties and that's where the Honda is to me as good as the Multistrada !
