One our machinning services that we provide for our Ducati customers is to reduce the weight on OEM dry clutch basckets for better performance and less rotational mass. this is the same hole pattern as the original Ducati Corsa steel baskets for race and "S" model Ducati's. Also the big advantage is you can use your oem plates and components without going through major expences. For machinning we would need you to send us your clutch basket then we will send you the CNC machined basket back to you via Fed-Ex insured. The turn around time is about 3 to 4 working days. Please contact us @ 818-771-1410 for further questions.
