Original fitment for the rear chain was 95 links of Reynolds type 110054, which had a pitch of 0.625 inches, roller diameter 0.400 inches and inner plate width of 0.255 inches. Those dimensions in metric are approximately 15.87, 10.16 and 6.48 millimetres.
sprocketsunlimited.com are well known in the UK and recommend two manufacturers of "Reynolds" chain: Iwis (German) and Regina (Italian).

That would generally be called a 5/8" by 1/4" chain?
Chain sizes in North America (so South America too???) are normally not indicated in sizes, but they have a number, usually 2 or 3 digits if I remember correct, Henri on the forum here will know, there's a conversion chart on the internet somewhere, but cannot find it right now, but believe you need a #520 chain
There is the same system for lamps/bulbs, they don't say 6V or 12V-25 watts, just a number, supposed to be easier!!
Cuando vayas a comprar las cadena pedí una cadena paso 520 de al menos 95 eslabones (pedí más por las dudas y la cortás a la medida).
Generalmente los fabricantes japoneses de cadenas las rotulan de ese modo. Pidiendo una cadena paso 520 y de al menos 95 eslabones no vas a tener problemas.
Cualquier cosa avisame.
