This kind of desmo has the following characteristics:
The separate opening- and closing camshafts are located in between the valve and the pivot point.
The cams run in the same direction because of the use of an extra (idler) gear.
The closing cam is located under and the opening cam located above the roller.
One roller (turning constantly in opposite direction) is used as camfollower.
