Hi everyone, i sell this slipper clutch STM EVOLUZIONE 90mm per those bikes that have dry clutch with M20 nut (I used it on a Ducati 999. On some bikes, such as 1x98, you have to change only the nut). The slipper clutch is the full kit version including the aluminum clutch bell and 48t friction disks in very good conditions. The slipper clutch is perfectly working and complete with all parts. I ask 600 euros including shipping from Italy (payment via paypal or bank transfer).
