Ok, so I def want to upgrade to a more modern fork setup, partly for looks, partly for stopping power/performance.
I recently snagged a good deal on a set of 2004 GSX-R600 fork tubes. So here’s what I'm thinking. I’ve been researching triple trees and bearing and tube diameters and crap so I can see what’s compatible. Tell me what you think of this. I went to allballs.com and went to the fork conversion link. I know that that the XS400 shares the same bearings with the FZR400/600, so I put 1988 Yamaha FZR400 in the converter and got the bearing size and all compatible bikes (and if you scroll down, you’ll see that, indeed, the XS400 uses the same bearings as the FZR). So I’m now thinking, maybe I can get a set of triple trees from another bike that uses the same bearings as the XS400/FZR400/FZR600. Great…but it seems that’s those sizes apply to older bikes with traditional forks, not inverted…but wait…not so fast! The Honda CBR954RR uses the same bearings and is an inverted fork. So I check the specs on the CBR. That uses 50mm tubes just like the Gixxer tubes I bought. I can just slide the Gixxer tubes in the CBR trees and theoretically have them fit right into the neck of the XS. Yea? Yea?
