Have you seen this? I don't think that it is available in the states.
I stopped at a Ducati/KTM/Harley shop in France and saw this. it is a cross between a MX bike and a Trials bike. Looks like Trials tires and frame and seat look quite a bit different then the MX bikes. The seat is a lot thinner then the MX bikes and looks like it goes farther forward and lower as well. the gas tank filler must be under the seat and there is a aluminum 1/2 of the frame and a plastic rear sub frame.
This would be a blast to fart around on in tight technical stuff.
they also had one of these -
