Unlike the "desmo" of ducati, the pushrod "springless valvetrain" makes no mention nor demonstrates how the pushrod (which is also now a "pullrod") actually works.

All the normal push only contact points, pushrod cup seats and rods have to pull as well now, as well as the very intricate camshaft lifter setup.

And by the looks of the lifter, has no rotation so does it have a roller follower or a "foot" like a SOHC engine with rockers.

I cannot see long term use of this setup.

And/or high rpm failure.
