Interchangable Rims?

[Roc64]

I am looking for a second rear wheel that I can put a paddle tire on so I can just do an easy swap at the dunes. Just wondering if any of you guys with more experience with these bikes know what other bikes wheels will bolt right on the the 400? Thanks

There are some KTM wheels that fit. Do a search for just that ?
