It may be, but from what the picture allows to see, it still has the Dell'Orto carburator (therefore not very much chance of important engine elaboration), it still has the electric starter motor (therefore not much care to weight reduction), I wonder what could he have done with the engine to make it different.
Nice fuel tank, though.
And the saddle... for a moment it seemed to me like the Arcore 125/150 one, somehow bent to that shape.
Which would be a real threat. But I'm afraid is not like that.
