The frame part which is damaged on most 70's small frames by fall or rust.
Fits models with long wheelbase. Finally available again as a true to original replica of the well-known Piaggio supplier Cuppini.
The old, carious part should be removed cleanly with the flex and roughing disc and then the new part should be attached with some welding points to the previous place.
Also recommended: the rear strut (Art.No.7671556) which should also be replaced within the scope of a complete restoration.
