That's quite a bit of scratch. I think you would be better served making duc swinger fit with spacers and some fab.I looked into this a while back. Greggs Customs builds them. We talked for a bit and he said he would do a ZX12R SS swingarm but it would be about $4k USD.
Another option was to use a R.A.M SS swingarm for a zx7/ZX9 and modify it a bit.
Here is one on a ZX10
converted mine to a single sider using the front off the zx12 and the back off a triumph 1050Hello all. Does anyone have any info on how to convert a ZX12R to single sided swingarm? I'm sure it must be possible to use a Ducati or a VFR. It would be great if someone ahd been down his road and could give me some advice. Thanks
