Not my cuppa tea but if diesel/mixed fuel is what appeals to you then this looks like the best available. Also has a 400 mile standard range = ~100mpg which can't be bad.

I think that is the one based on the KLR650....and developed with Cranfield University....it should run on anything even 100% biodiesel.....

Welcome to Hydraulic Innovations

It's no dual sport but you can order plans on how to build it. :funmeteryes:

It is my opinion these things are 'vapour ware' and will be readilly available just after 'Windows 2027' is released bug free.

You will need to scroll down to the Trak bike

I am off to the diesel bike rally tomorrow morning in Hamm Germany via Ypres and Passendale.

Wow diesle, they better turbo charge that thing, I need fast pickup from gasoline not that slow power build from diesel. interesting though....

Veggie Oil?
 

Do you know if these things would run on veggie oil conversion?

Don't hold your breath lads, this thing has been "coming soon" for years, which is annoying as I want one. At this rate I'll have to join the army.

Ludicrous off road range anyone? Yes please!

Oh and plastic fuel tank so that you can see how much you have left, how cool is that?

This bike has been out for quite a while, however the US marine Expeditionary Force keeps buying them up and none are making it to civilian hands, that I know of. I was told be a friend in the marines that they can run on multi fuels, Kerosene, gasoline, Diesel, Camping fuel etc including biodiesel.
I cant verify this other then this is what I was told, and I did read on a webpage it was a multi fuel bike and this listed gas, diesel and kerosene as "some" of the fuel options. It would also be my guess that your fuel range would reflect your choice of fuel. I would also question Fuel Filters and Fuel Pumps such as sulphur free diesel etc. My other concern would be can fuel be mixed int he tank, or would one need to empty the tank before changing the fuel, so the timing was able to adjust to the fuel.
I did read on diesel it was making something like 8OMPG or something and was said about increased mileage in the future developments.

Hope this helps, When I get home i can look into the links and see if any are still active, as I got them liker a year ago or so.

be safe!
Fenian!
