Rear Disc What Model?

[taggat]

Hey guys,

Im wanting to put 18 in. rims on my 650 for a pure street tracker build.

Does anyone know of what model xs400 had a rear disc setup?

Can any of you confirm that the xs400 ran a;

3.00x18 front, 3.75x18 rear?

I know for a fact that the 1979 XS400 F had 18" alloy wheels with disks front and back. I am reminded every time I go out to the garage. But the XS400 ran much narrower wheels than that. 1.85 f and 2.15 r.

Maybe my source meant the max tire width he would use on the 400 rims for a 650.

Do you happen to know the axle diameters?

I have a set of xs400 rims but there early 80's I believe with a drum.

If you have any spares laying around Im very interested!
