Which forks are interchangable with a curvy? - Page 2 - SV650.org

R6 are 43mm, SV are 41.

You could machine yokes out, maybe, maybe not. Lot of messing about.

What if you changed top and bottom yokes over? I don't know what size the spindle thing that goes hrough the headstock is on either..

Go for it, that would be loads less hassle than fitting GSXR parts. When you do that you've got to change the top and bottom yokes over

GSXR 750 91 & 92 (not sure when the bearing spec was changed, maybe with the SRAD) uses the exactly the same bearings as curvy 99 - 02, so USD forks, with the minimum amount of faffing around, although you'll need to sort the speedo out, as the front wheel off this year runs off a geared drive and not the magnetic sensor that the SV uses. Unless you get an engineer to make up some spacers and a spindle to use the SV front wheel. You'll need the GSXR discs as the SV ones won't work with these forks

Yes SRAD was when they changed the bearings.

WN/WP yokes don't have lockstops in the same place as the SV. You will need to cut them off.

I have a very big angle grinder

Then make more lockstops.
Lot of work to save the hassle of buying a bearing. And you end up with much heavier forks, smaller diameter discs, heavier wheel etc etc Also forks are old tech and not as good.

I don't have an SV or I might have done, But then I would have probably just machined th eold yokes to fit if I was doing it.....

But is that safe? Are you good enough to do it with accuracy which this demands?

Yes, you're right, although better than OEM SV forks?

How about swapping newer forks into the 91/92 yokes, fork diameters are the same aren't they?
