Guzzi demands two internal reinforcement tubes for the 250; he complains of a small cylindrical hole in the center of the valve flare not foreseen in the drawings: “this is done out of carelessness: please notify the plant manager of this, because it causes self-ignition”. Finally, the necessary reinforcement to the pivots of oscillation of the fork. A striking example of how important racing is; not only for prestige but above all for product development.
From TT to series production.
