belt drive is on the wrong side, cant switch swingarms because the shock mounts in a very different location, most likely because of clearance issues.
I would tend to believe that it would be simpler and cheaper to just adapt a Cr to look like a cg
pod relocation or EBR front radiator swap out the headlight and flyscreen tail swap forks fully adjustable rear race shock and fab in mounts for a chin fairing.
I have seen pictures where somebody did it already (cr to lightning look alike) sans the ride height adjustment.
