Pretty cool, wonder how programmable the controller is.


Also curio7s the rear axles theyre using to get that much travel and not bind

First, impressive linkage..

idk where you want to go with this thread but I'll put some stuff out there 

100% camber compensation with roll and no camber change in pure bump, sounds like a beam axle.. But this concept has large changes in track width during pure bump, bummer.. 

Problem is it relies on the driver to shift the CG (or did I miss something?), thus not useful for any fixed driver vehicle that will roll out of the turn.

I6 it has a control box that controls the rams that lean the vehicle by using steering inputs.

You can't have much travel with this independently. Also with a fixed driver will be necessary a sophisticated electronic/hydraulic tilting control system. 
I would not be much amazed with the drifting from that video, probably a over reduced transmission plus too skinny tires for application. not really related to the suspension.
Many concepts we use to control the vehicle roll does not apply to a tilting suspension, this was intended to make a small track vehicle have more stability on turns and primarily make trikes rides like a common motorcycles.

It doesn't seem like the rams are controlled by steering input. If that were the case, it seems that the bike would lean the other way when he is correcting the over steer out of the corners. 

At the beginning of the video, he leans the suspension by shifting his weight, not turning the bars. 

Would be a TON of fun to ride for a couple hours

it says on the technology tab that the tilt is electronically controlled, it could be referring more to the snow mobile version of this system.  As for lack of travel, there's images in the gallery of the 4 wheeler "flexing" its full 24 inches of travel.  Thats why im curious about the axles being used.  I don't think i would try to incorporate it into a baja as packaging and the weight penalty of the system would not in my opinion be worth it given the limited power.

The independent travel is very limited, after that, it affects the other side. That's tilting plus travel, but looks not functional in this position.
I'm really skeptical about this picture, i'd bet the cvs are disconnected from the shafts. Just like the shocks.

Well, after seeing this other pic... 



thats not a small-travel system like the other tilting suspension i've have seen before. But seeing the video we can see the the travel is almost all negative, the positive depends on the tilting.

But the flexing pic still looks suspicious to me.

yeah i just wanna know what axles lol. that to me would be the most beneficial part of the whole set up as it relates to baja sae because the added travel would be nice

They have a patent for their differential that shows the CV joint design:

It uses a floating design, i.e. plunge is taken up by the splined portion of the inner CV joint (126). It also has a unique centralizing bar (120) that is claimed to aid in stability at high speed/misalignment. 




They have another configuration where plunge is taken up at the center of the axle..
