Had decided to delete the spare wheel in favor of a foam can. About half noticed some here sporting a box to stow stuff instead. This morning had a dedicated look.
Seems there are (at least) three versions one of which much to my surprise was Pieza montada de origen en modelo: Vespa 75 Junior; standard on the MotoVespa 75 Junior: not only unique to MotoVespa 75 cc, also the only PK without indicator lights and apparently the only with OEM stuff box? Cool
Think I will order this sleek variant. Not only less obvious, also cheaper and less spacious is not all a bad thing.
