Best solution for a motorcycle simulator?

I am toying with the idea of building a motorcycle motion rig, as I am getting to old (& afraid) to be racing like insane on the real ones....

But what is the best solution? On YouTube there are ones that seems more like a childs ride-on than a simulator, as they are doing all the motion, unlike the real ones.

But then I saw this:

That makes more sense, but then I think it lacks motion!

If the sideways action was done by the user shifting his weight, a motor could be used to make the surge and braking and pitch, but then the user can't control the weight distribution front to back?

What would be the best solution?

I think like @noorbeast that it may be possible via a combination of motion and G pressure systems and sensors, but best to use VR, as your trying to fool the brain that the bike is 'tilting' through turns which it would not be, as it would give a unrealistic feeling due to gravity. Not a simple project to get right.

Thanks
I've read through the old posts, and there is a lot of great ideas, but it doesn't seem like anybody has actually finished an active simulator?

It would need to be simple I think, maybe just passive steering by bodyweight and 2 motors for pitch? But then the leaning would be a problem.. It could be solved with a button, but don't know if that would feel right... That would be a Lean GP, with active pitch angle.

VR would be great, but there don't seem to be any motorcycle games out there supporting VR?

cruden do one - basically a bike ontop of a 6dof

I agree that it will be much more complicated if we aim for maximum realism, but maybe its possible to have fun with less?

The centrifugal forces are hard to simulate, so the lean angles must be a lot less, and I can't find a way around leaning forward/backward and simulate pitch? Only solution that I can think of is to simply use a analog stick for leaning and let the motors simulate pitch?

But if used in VR I think that even small angles and real peripherals will ad a lot of immersion, but maybe less than we are used to in car-sims...

It does not lean much, but you would fall off !

For it to feel realistic it needs to flatten out once you initially lean into a corner and or have a system that pulls/holds you into the seat like centrifugal force does. I do this for Aircraft sims via my G vest which pulls/moves me in the seat mimicking centrifugal force, while the whole rig still pitch/rolls as a real aircraft would via the 6DOF setup - very realistic . Not so easy to do this on a bike sim, as you still need to be able to move around freely.

I'm not sure I understand? Why would I fall of this?

I think we have to forget the centrifugal force, just as we (mostly) do away without any g-force in car games. The problem is that its that force that holds us seated on a bike, but with less leaning this shouldn't be a problem.

That would be awesome, but overly complicated and would require to much work every time you would want to take a ride...

When using my sim for VR airplane games, the brain is easy enough to cheat into thinking that the angles are much bigger than they actually are, which makes me think that it could work on a motorcycle sim?

yes it may work - need to speak to somebody who has tried one for some comparison
