I just saw an in-depth TV segment on this project. One of the things that was clearly demonstrated, was the ability of an amatuer rider to corner extremely quickly on the bike. Personally I think it's ugly and the riding position is poor (from a posture perspective) However the design works.
I think of this as the motorcycle equivalent of shape skis to the average skier. You could be a mediocre skier and with shape skis, carve some lovely turns due to the design. This bike will do essentially the same thing, plus you don't fall as far .
Our greatest challenge in life is living up to our own potential.
