The front one might. The first gen (04-11) VStrom 650, the front wheel would bolt up to a second gen SV. I don't know if the later 650 Stroms are the same, and I don't know if gen2-gen3 SV wheels are compatible. There was no XT version of the first gen Stroms.Someone sent me via facebook this store, from France:
But it is super expensive too, over 2500 euros, impossible to me.
Procycle looks nice!
I'll try DL 650 xt hubs to see if it fits in the SV.
If yes, it would be much cheaper to find use ones.
