Hello Poumpouny,
and thank you for your feedback, i always consider than more brains are on a problem, better the solution will be at the end !!
And about what you says :
About natural mouvement, as i said i spent hours this last week analysing the mouvement, even put the GoPro of my son to film my hands and handlebar on my Pan European or on my other son ER-6 Kawa and i found on images what i was doing without really knowing.
And this mouvement, despite what you think, is or begging natural to me as every motorbike riders that ride for a while.
About the horizontal axe moved by the fact that i counter-steer on the vertical axe, this other idea (i post the "old" one - from 2 days) and this one is the news one from this morning at the breakfast time.
And i think that will absorb more the bike leaning mouvement to not trouble the rider leaning movement. Or, if it perturb anyway, i will have to make the rider leaning harder. I want to try anyway because that's how it feels to me.
About EdTracker Pro, that i use since it's out on the market, i will only put the Back and Front rider leaning.
I will be seating on my chair, not on the frame that's gonna move left and right.
So yes, want to ride a bike seating on a chair looks akward but that's the challenge.
About FFB, yes, i would love to FFB my vertical axe but i'm not sure (that was my question to DD) that the FFB is actually to copy the reality, meaning bloking me to turn if i brake hard, as in reality. And on a race, guys are allways braking to late and have to force down the bike on the side they want to go. Its natural centrifuge and centripete forces, plus the gravity and the wheels inertial mouvement. On the regular street bike, you brake, turn and the accelerate, on a race bike you gonna brake and turn but still brake on your turn (on the angle) so braking will have a tendancy to make the bike stand back up to the vertical and is going to refuse to steer and then you have to force it to put it into the curve, that's what i will love to find with FFB but i'm not sure it acts like that. (where to catch the data for that ?, as i wrote somewhere else, as a Motec in racing cars).
And about DSA or DST i have no idea what is it, information in here and about the game is an archeology type of thing, so if you know what it is, i'll be more than happy to learn about it...
(what you say about vertical axe is interesting and i started to draw something like that but the draw isn't finished, i'll give it a try to the end of design and post it in here)

Edit : what you couldn't see in the other draws is that the horizontal axis on the handlebar is at the same axis as the riders leaning axis. So if i push my handlebar in a horizontal plan (to counter steer), it won't be pushing the rider leaning left and right.
And if DSA or DST doesn't give any feedback, i was thinking of using limiter after calibrating is done in order to give myself a max angle of 60° or something around that. (today, i'm using a joystick and a drum pedals with EdTracker on it for the rear brake, it's a catastrophy !! and i have no feedback anyway so...)
