2007 Nevada 750 Front Axle diameter

[saguaro_squeezer]

Continuing my quest for a replacement wheel for my Sputnik sidecar.  Currently has a BMW snowflake on it.  I found a good Nevada front wheel on flea-bay.  Does anyone know the front axle diameter of a Nevada 750?

Thanks, dibble.  I know that a lot of the small blocks use the 92204221 bearing.  I'm trying to see if that has a 17 or 20mm ID.  I've not found it in online searches yet.

A V50II has a 17mm spindle and it isn't on that list so is a nevada 20mm?
