I picked up a 3/4 inch drive socket from the Ally Pally Show for £5.00 and a 3/4 to 1/2 inch adaptor for £4.00 and there ok, I would suggest that if you want to do the job properly then you remove the wheel, tap the swinging arm and do not forget to torque the wheel nut correctly, All torque settings can be found on the Ducati.Com site. Good Luck
