Original Piaggio cylinder for the Piaggio Fuoco and Beverly Cruiser models with Ø=94mm bore. Can be used as replacement for the old cylinder with only Ø=92mm bore. This gives the 500'er Master engine real 500cc (Ø92mm = only 470cc!) NOTE: The cylinder with Ø=94mm bore has a shorter cylinder base than the version with Ø=92mm bore, but is released by Piaggio as a 1:1 replacement. AI-translation
