Nunique rides a 2001 650GS with the standard 19 inch rim on the front.

I have a Dakar 21 inch rim, which I would like to fit on there.

Obvious differences - GS wheel - 100/90/19
Dakar wheel 90/90/21
ALso the Dakar rim looks much narrower than the GS rim.

The main reason for wanting to change is that it should be better off road with the bigger rim, BUT will tar be as good or better?

Should I look for a 100/90/21 front tyre, and will it fit properly.

Will it be a simple take one out, fit the other wheel, or do I have to do the entire front end? I would ideally like to keep her brake disc(still in great shape) have not measured the different discs.

What is the view of the dogs.
