ZX12 swing arm swap big pics warning!
I am in the process os swapping a friends ZX12 arm to a 05 ZX10 arm.
We will be using a ZX10 rear wheel, rotor and caliper as 12 wheel hub is too wide to go in the 10 arm.
I want to see if I can fit the ZX10 wheel up also but that will take some more time. ZX10ryda was kind enough to give me one of the dimensions I need to see if it fits.
You can mount the entire ZX10 front end but there are pros and cons. You get radial mount brakes and a lighter wheel but the forks are shorter and require the use of a different bar set up or clip ons which cause faring clearance issues. If you have a 2000 to 2003 12 the brakes may be an upgrade but the other problems don't make it worth the hassle in my opinion which is why I want to see if the 10 wheel will fit so they match.
I am mounting the arm with a hybrid ZX12/10 pivot I machined along with spacers to match. Everything should be a bolt in affair once I get it done.
The 12 uses a 25mm pivot and the 10 uses a 20mm. The threaded adjuster on the 12 is 32mm and the 10s is 30mm. There are a few other differences but those are the major ones. I will post it all up once i get everything mounted.
Others have use another method to mount the 10 arm and while they worked I wanted to try something else.
I will update this when i get some more work done.
I have the spacers machined but no pics of those yet. On my days off later this week I will be test fitting the arm and take more then.
Started as this lump os steel like this shaft. Several hours later it is finished.
