APTC how it works

[caperix]

There have been alot of questions about the APTC clutch used on many new ducati models latley.  I had one sitting unused in my garage so I took a few pics to clear up some issues on its operation.

The "slipper" part of the clutch is all contained in the clutch hub.


In the rest position the 2 parts of the hub are separated by spring pressure allowing the clutch to slip.


The hilical cuts in the hub over come the spring pressure pull the 2 halfs together when power is applied.  This is when the clutch is fully disengaged.


I do not know of any one that tunes the slip characteristics of this clutch but I think the main area to look at would be these 3 springs under the pressure plate


I hope this helps explain the clutch better.
