Three Wheel drive Sidecar Rig!

Came across this photo on https://anunciautos.com.br/blog/2009/09/side-cars-para-motos-todos-modelos-imaginaveis-e-inimaginaveis/

Unfortunately the site does not give info on the rigs shown, but this one intrigued me - I can distinctly see a driveshaft going to the front wheel! Wonder what that's like driving? The fairing is a BMW R100/80 RT fairing, with some "MINOR" changes.... ???
