Hey guys what a great thread! Ok Im still looking and reading around but I checked the serial number and my Nishiki says KS171108 so it looks like it was for the US market pre 1975! I just did a 160km leisure cycle on it and a guy said that my bike must have been old, I thought yeh maybe the eighties but I didnt think it'd be seventies.. could it really? Ill take some good pics, its not in its original state, I have it as a commuting racer.
nice one for the thread!
