Sport Bike Fork Lengths

So one thing I do a lot during a build is to research what fits what.

It’s always a quest to figure out if the swing arm for a 2004 Suzuki GSXR750 will fit say, a 1975 Kawasaki Z1, if one is so disposed to try such a thing.  I tend to want to try such things.

But there are so may variables; swing arm width, swing arm length, swing arm axel diameter, rear axel diameter, shock mounting position, (could one weld mounts for a twin shock conversion?).  A lot of the numbers are hard to find, as they’re not really that pertinent to the average owner of, say, a 2004 Suzuki GSXR750.  He probably doesn’t pass the winter evenings scratching around the internet to answer the burning question: What is  my swing arm axel diameter?  But I do.  Specifically, I want to know YOUR swing arm diameter, cause I might use your swing arm on sumat’else.

To this end, I’ve decide to start compiling what I find here, so I can find it when I need it again, and others may save some time on this task before heading off for another “Can you use a small auto fuel injector for a 4-1 intake on an inline 4…”

So, as mentioned, this is 2nd hand at best, and appears to be more than that.  No reason to doubt the numbers, no reason to trust them,  Found info, maybe worth every penny, maybe not (in plain English: trust the information below at your own risk.  Verify measurements prior to application, do not do anything that would intentionally or unintentionally harm  yourself or others, try not to be stupid, call your mother often, floss daily…)
