I don't really want to use one from a ZRX1200 as already used that twice before, maybe a XJR1300 will do? Ordered one, only £50, and from the look of its pivot area, plenty of meat on the arm to machine it down to fit the old Zed frame if needed....
Note that there are two versions of the XJR1300 swing arm, the early version has a 20mm wheel spindle while the later version has larger spindle. I got the early version, as the Z900RS rear wheel I want to use also has a 20mm wheel spindle.
Of course the pivot spindle is a larger diameter at 20mm than the original Zed spindle at 16mm. That can be solved by either modding the frame or using a Zed spindle with top hat spacers to make up the difference in the swing arm. However, after a lot of research I found that the bushes used in a Suzuki GS1000 are the correct size to allow the standard XJR bearings work with the Zed spindle. While the swing arm pivot area only needed narrowing by 10mm to fit the frame.
Its a nice looking arm, on this project it wont be left anodised or polished.
