Do your NC750X DCT behave the same way or is mine f..... up??

Seems like you've been flogging it in S mode a bit? So it will need special soft riding to consider 6th
In D your 6th works normal. I suspect S has learned this behaviour. You can always reset your DCT computer. There is a threat on it here can't find it though.

Has anyone successfully taught their DCT to shift at a different point? If so, how?

I'm just trying to understand the often repeated statement about the self learning feature of the DCT. Sounds like from the few comments here that perhaps the clutch actuation mechanism may have a self calibration feature. That might explain why kpinvt saw improvement over time in the smoothness of shifting from second to first. This would be an optimization of the mechanical operation of the transmission, not an adaptation to a particular rider or riding style.

IMHO The whole *point* of S mode and the learning part, is to hang in each gear as long as possible prior to going up, if that's what has been input for it to work from under prior conditions. In your video, it appeared that you were complaining that the bike didn't shift into 6th when you were higher up in the rev range in 5th. Well, I'm confused. To me, why would it have shifted? You weren't anywhere near redline, and in sport mode. That strikes me as the DCT's ECU *did* learn, that it shouldn't shift any earlier.
Again, I'm only replying as how I'm looking at the problem presented. Did you ever put it in Sport, and then whack the throttle full open, not backing off at redline? You did this and it still didn't shift into 6th? Or did you always simply roll on the throttle and then leave it there, expecting the bike to know that you wanted it to arbitrarily shift up?
Also, isn't that what the ability to manually hit the shifter button is for? To override the current dynamics of a situation, as suited to the rider at any given point?
I hope my tone was OK, I'm not trying to be disrespectful. I wish I had taken the time L.B.S. did in his reply. I like the bike, not everyone will.
I left a piece of info out earlier: The Silver Wing I rode 20,000 miles in 2 years. The BMW G650GS I had for the 3 years after the Honda I rode 12,000 miles total and the PC800 that followed the BMW I rode a total of 2,500 miles in 2 years. The PC was my "Dream Bike" that I found too painful to ride for more than an hour. Buying the DCT NC is an attempt to get back to high mileage riding.
Hi L.B.S.
Thanks for you answer.
When doing a slow acceleration in "S" mode I was actually expecting the DCT to shift to 6 gear before the red line. If I just twisted the throttle fully open, I would expect it to hit the red line before shifting, and in this situation it would be ok (and it does).
The only thing that I am saying here is that the difference between D and S mode it too big. I feel that I can choose between to extremes.
In S mode we are talking about hitting the red line above 140 kmt before it shifts to 6 gear. In D mode it shift to 6 gear at 65kmt. It seems pretty extreme to me. Yes I know I manually can hit the shifter button, but that's not why I bought a DCT. I really miss a "normal mode".
Please don't tell me that I just can buy another bike... I know that I really like the NC750X and there is more positive stuff than negative, and I think that the solution that works for me, is the foot gear pedal add on option.

As far as I know with the foot shifter installed you can still make shifts with the buttons on the left hand grip. Maximum flexibility. There is a video on YouTube from a fellow in Scotland, I think, that shows his DCT bike with the foot shifter. Here it is:

I've seen this several times so now I can tell what he is saying.
Here is three more:

I haven't seen the last three yet, just found them.
All this discussion about DCT learning capabilities is a "Déjà vu - all over again". I think that everything started with this Honda Tech Views Q & A about new DCT, sometimes in 2012. If I remember this function was mentioned by many bloggers and by Kevin Ash also, (and that NC700 engine is a half of Honda Jazz/Fit B.S. story) before first NC DCT showed up in U.S.
After almost 3 years my DCT is as dumb as new - didn't learn anything.
I never noticed a problem with downshifting from 2-nd to 1-st. But I always have a nasty lugging on 3-rd gear at 16-19 mph (26 - 31 km/h). Now if I'm able to predict that situation I downshift manually.
That's why I don't believe in any such thing as learning function. Another red flag in the same Q & A article is a statement:
"...Dual Clutch Transmission system's ECU is programmed to minimize unnecessary gear changes by monitoring riding conditions on curvy roads like mountain passes..."
In what world? You need a load sensors, traction, cross wind sensors, you name it.
I challenge anyone to show me anything, in DCT system diagram below, even close to resemble what would be required to achieve gear shifting learning. To execute shifting program, speed control sensor and throttle position sensor are enough. And this is only what we have in our DCTs.
