1) I do believe your ST has a 12 tooth clutch pack, and that has lasted longer than a race.

2) I have and do fit my own.

3) really a mix of the above 2

4) To my knowledge the majority of road going dukes are supplied with dry clutches, whether used on road or track.

5)ALL dry clutches will wear quicker.

I would say a slipper clutch particulary when fitted to a big twin, is one of the best investments you can add to you bike, whether a wannabee or not!
