I'd stock the 120/90-18 M/C 71T, it has the higher load index and the higher speed rating. It is the size for the 1981-1987 R80G/S and it is a perfect tire for it! I don't know why the h*ll the US distributor would not import it.
Probably because they'd only sell 10 tires in that size per season in the US and Canada.
