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! |
