Nope, that's the Autotech stress bar, with a single diagonal brace.  The
Eurosport one had dual diagonal braces, shaped like an X..  I agree that
the rear bar does nothing other than act as a mounting point for the
diagonal braces, and that while a single diagonal is sufficent to create a
rigid truss, it does to at the expense of creating unbalanced force at the
front A-arms.
