Offroad 21/18 inch rims - plug and play on Motard?

I have a qm200gy-ba. I will use this trough the winter season in Norway, so I need to use winter tyres with studs. Unfortunately, these tires are designed for the typical offroader with 21 inch front wheels and 18 inch rear rims. My Motard has 17" front and rear, so my plan is to buy a set of 21/18 inch rim from the qm200gy-b cross - along with a new speedometer drive.

Can anyone confirm that these rims will fit my motard-version?

I have replaced motard 17" rims with the dualsport 18" & 21" without any problems. Not sure if it's the speedometer or the speedo drive that you will need, but other things should be OK.
