Briderdt, the last pic is being presented as the best setup, pic5. In this one he is raising his center of gravity which allows for less lean, which is the important thing. And is this necessary on public roadways? Absolutely I say. It is not about maximizing your speed through the corner, its maximization the traction you have available to you. And it is on public roads you need the skill to adjust mid-corner, due to those unexpected obstacles.
