Behold - the desmodromic valve actuation.
One of the Ducati myths of constant 'valve adjustments'. After broken in, and assuming not full on racing the bike, the valves should remain in tolerance.
Another reason for my opting for a 2V instead of a 4V. 2V would be easier to do the valve checks, and rather than buying a set of shims, I'd just buy the ones I needed. Saves $$$ from taking it to the dealer. Tons.
