John Baron sent along this e-Drawings file of the test rig showing an adjustable mechanism to compensate for a variety of rider weights. On Morph II, we calibrated the shocks to work for Rory's weight. This worked very well, but doesn't work well for showing other riders. And its not practical for production.
So, one of the goals of the new morph is that it handle a range of rider weights with a simple adjustment. That's what John is testing here.
While Morph II had the frame as a single member, and had two gas shocks, the new design puts two frame members on the outside and a single shock in the middle.
Here's a bunch more photos.
By the way, the gold-colored mechanism is the automatic seat adjuster. As you morph up, it tilts the seat back by droppiing the rear of the seat. This corrects for the forward tilt that morphing up causes.
