I was disappointed to see here that I'm not the first person to realize a hydraulic final drive may be an excellent fit to this sort of design :)

Someone did a hydraulic final drive motorcycle: http://www.hydraulicinnovations.com/

I have a couple models at the url in the subject of two seater motorcycles with gas or electric power, and a full cowl, and a single seater scooter based (much simpler final drive) model with a full cowl. And a few car ideas. I think they're all pretty realistic, no massive chopper flop, significant consideration for final drives, no massive clearance / cornering issues as in Kaneda's original.

Not so keen on the choppers but I love the "raccoon".

An old Portagee blacksmith I used to know built something like
the Raccoon in the early seventies.

A couple of years later he turned it into a rototiller.

By hydraulic final drive I mean replacing the chain or drive shaft in a motorcycle with hydraulics. A lot easier to get under a much lower seat than a chain or shaft. At least I think it would require less massive modifications to existing transmissions.

yes. excuse me I'm not a purist, does the hydrolic part of the honda only concern the automatic gear box then with still the use of a shaft ?

I think yamaha used it on the front wheel of its 2WD dirt bike then.

The hydraulic part of the honda DN-01 only concern the automatic gear box.

Final Drive: Shaft

DN-01 -> Discovery of a New Concept 01
HFT -> Human-Friendly Transmission
