Axial to radial caliper conversion

Greetings
Has anyone found a manufacturer or supplier of a conversion kit (plate) from axial to radial front brake caliper?

To be honest, I'd doubt anyone would do that. It's a lot of work and time for a very small market, so I'd guess they would be prohibitively expensive (and clunky/heavy to add to the fork legs). You'll also need to factor in the cost of the actual calipers and the master cylinder.

Better to do a front end conversion for one with radial brakes (GSXR 1000, as Fred has done) - not cheap, but a functionally better solution.

You know I have 2008 gixxer 1000 front ends on three of my bikes. I had extensions welded to the top plates on the  three sets. I have on my bikes now. Sold the extensions I had made to Fred and others on the forum. I was riding the 92 that I just bought. And I was like. Man there's something wrong with the brakes on this thing. I stopped a throughly checked them out. They are mint. Good pads no oil on them. Good disc's.  Then I remembered. It's because I've been riding bikes with the gixxer brakes. I  forgot. How bad the stock brakes are compared to the gixxers.  :pardon:

They welded the tubes onto the plates and machined them down to match the diameter of the forks. I made them a little longer so I could slide the clippon bars up about an inch for slabbing. Then slide them back down when I got to the corners.

The best braking set up I've seen on a FJ Dan, excellent craftsmanship. :good2:
