You should also ask this question in the Hacks section, as 99% of the Ural in the US run on 3 wheels.

This was myine in the early '80's. I didn't fit the engine, I got it as an unfinished project, and was it always an ongoing project. It had a Jupiter chair on the left. It was a bit of fun, top gear powerslides left and right, but with the VW having lower revs than the Ural engine top speed was down, 100kph all out I think.

Corvair motors run counter clockwise. Used to be Corvairs, a couple of Buick motors and marine motors ran counterclockwise.Now it maybe a ton of motors. So if you put a corvair in a Ural. It would have 4 reverse gears and 1 forward gear. If I'm wrong or sorta wrong, someone please chime in.

OK, so set up a reversed oil pump and distributor, put in a set of reground cams, and run the engine backwards. I swear, y'all act like it's the friggin' apocalypse and nothing that doesn't already work can't work.

(j/k, sorta. It's non-trivial to reverse engine rotation, but it's not impossible.)

Back when mine was done, early '80's, although we had some Ural's come in in the early '70's, there were no parts. So it was too expensive to rebuild the Ural engine, you were hardly likely to find a BMW engine lying around, but VW's were abundant, it was just a marriage of parts.....making something go out of 2 things that didn't.

Corvair is a BIG six... Not really suitable. VW four is compact and very suitable. Performance/repair parts ABOUND, that equals CHEAP!!! Like KLR cheap!

Running a corvair backwards is/was common, to use with vw trans in buggies, as was flipping the ring gear in the trans for eliminating the need to do so.

12a or 13b adds lots of weight and cooling system complexity.

VW is capabale of doing virtually everything you'd want for a project like this, except sustained high rpm. Might be worth adding a simple custom gear-up box between the VW and Ural to eliminate the need for it.
