Urals are known for having a 2 wheel drive option, but this is only available with the chair on the right. Some builders have come up with their own designs for more than one wheel drive.

What about using the workings off a quad bike swingarm?
What about using the inner workings of a quad swingarm for 2WD? This one is a Suzuki LTZ400 Quad. I’m sure it could be cut down and made to work but it would require a fair bit of fab, the wheel would have to be fixed to the axle with the axle rotating in swingarm bearings, rather than the wheel rotating on the axle as they usually work.
Here’s serious 2wd unit, originally based on a GSX1100F there’s probably not much of that left, it’s now powered by a GSXR1100 taken out to 1250cc thanks to Suzuki Burgman 400 scooter pistons.
The 2WD system is driven off the front sprocket and a driveshaft passing under the bike to the sidecar wheel.

I’ve wondered if this would work and presume it does.
