Has anyone used gsx1400 as pivot point is 236mm in length thanks kind regards DerZed
The frame width is 235mm and you need to account 1mm each side for the end caps so the maximum width you can use is 233mm.
Any arm that is wider than that will need material machining off the pivot.
You DO NOT jack the frame to fit a wider arm..
I currently favour XJR1300 arms which needs 6mm removing from each end.
The bearing tube needs trimming the same to suit and the frame shock mounts need extending out to match the width of those on the arm.

The GS1100e is narrower than the Kz frame. It’s a good option.

I am using a GSXR600K arm which is 235mm with the caps and will take a 180 tyre, the KZ inner races and bearing spacer fit perfectly inside the Suzuki parts and you just need a thin shim either side

Listen to Mikaw. It's a dead simple swap and has been done a million times. The GS11e swing arm will take a seriously wide tire. I had a 160/60 on mine years ago.

Don't be ridiculous! It's only a flesh wound!

Will that take the 5.75 inch rim that he is running (I am guessing a 180 or 190 tyre)

I don’t know 100% it will work but so far in my mock ups it’s fitting a 180/55/17 on a 5.5 wide rim.
