Yamaha Pro60 specs?

[TooQuick]

I'm looking at a 1992 Yamaha Pro60 in a local classifieds and can't seem to find any info on them, so does anyone know the difference?
are the gears the same ratio as the regular 60?

thank you

oh okay thank you. Do you know if there are any other differences between the 60 and pro60?
