I found this on a Dutch site while taking a look at their diesel bike.
This was the bike I was looking at when I found the 2WD.

It's crap.
Two wheel drive works in the desert, and in mud. Otherwise, it's a maintenance & weight penalty no one wants. Yamaha has used it (Ohlins built & designed) in the Dakar, and after all, they did better w/o it. I bet that pig in the picture above weighs 500+ lbs. If it were real.
