On the left side of the KTM 950 mill, I see the cherry on top: auxiliary chains running up from the countershaft sprocket, under the fuel tank, to just behind the steering head. A Christini two-wheel-drive system uses two counter-rotating shafts that drive the front wheel when the rear starts to spin. Perfect for piles of rebar and wreckage, I think. I pick it up off its side, surprised to feel only the weight of a jacked-up FZ-07. A tall 400 pounds.
