While I don't have an answer for you, I will suggest that you don't ignore other brands. It is a matter of what will physically fit the bike.
- The hub width has to fit into the swing arm. Most bikes use spacers to center the wheel in the swing arm, and these can be fabricated as required.
- The stock axle bolt will determine the bearings required in the wheel. If the new wheel has a different sized axle bolt, that will take some research to find bearings that fit the new hub and your axle bolt.
- Are you willing to convert to rear disk brakes, or are you trying to find a wheel with a compatible drum brake?
- The rim diameter and tire size are restricted by what will fit your swing arm. Most modern rims are wider than our old school rims, so you will probably be looking at older bikes to find a narrow rim that will clear the swing arm and chain.
I'd suggest that you look for 17" or 18" rims since I understand you are interested in making your bike into a Dual Sport. Those are the more popular DS sizes. And spoked wheels are generally preferred as they are easier to repair than alloy wheels.
Have fun and let us know that you find!
