Axle sizes?

[Junkie]

I'm looking at picking up a GS, and have a set of 17" SuperMoto wheels for a Husky TE610 that I'm interested in making fit on it. Because they're spoked wheels I can adjust the offset for the wheel to be centered properly, and am happy to shim rotors/sprockets for proper offset, but the axle diameter requires some machine shop work otherwise. My wheels have 20mm axles, what size does the GS use?

thanks for the help,
-Daniel

Front brgs are 15x42x13 and rear brgs are 17x47x14 so axles are 15mm front and 17mm rear.
