I've been wondering why no companies have produced and sold hydrostatic drive motorcycles, eliminating both the transmission and chain or shaft drive.
They're used on everything from tractors and combines and both my mowers use them. They're obviously not short on torque and although the creation in this clip is a little crude, it seems like a motorcycle-sized pump, drive and associated hoses would be rather small. The two drives that power my Gravely zero-turn mower are about the size of my fist. The pump probably wouldn't take up any more "engine space" than a regular geared transmission.
I guess it would kind of suck to ride a motorcycle without a classic geared transmission, though.
I see some "chopper fabricators" are coming out with diesel powered, hydro-drive creations and it's not like they have huge components and 1" rubber hoses sprouting out everywhere like this "Racoon" does.
I suppose it's all a matter of cost, though. Those systems aren't cheap but it seems since they're being applied to all manner of wheeled things, the price would go down.
On the other hand, having a hydraulic hose blow in front of your rear wheel on a curvy highway would be bad news.....Seems like this would be more of an application for a kind of off-road "utility" motorcycle.
This "Racoon" is pretty cool.
