I have a shop here looking into this for me but would like some input from the Ducati gurus. I have an early 900SS with the 17mm front axle. I got a good deal on a magnesium wheel which came off a slightly later bike with the 19mm axle. I am trying to figure out what parts I need from the later bike to make this fit up. The shop I spoke to said it should be doable without inserting a sleeve by using a 19mm axle, but they aren't sure yet what other parts are needed such as speedo drive and or any spacers. Thanks in advance.
