Thanks Cdn and bbrick. I was thinking in that range as well $1-200. Someone should want a spare - I usually get spares for my bikes with a new tire ready to go. Or, in the case of the dual sports, dirt or street tires.
My 87 LM came already converted to the 18 and I like it that way, even with the reduced offset triples. But I do like it better now with the earlier triples with the bigger offset. The 85 is being made over into a 1000S with wires, so the 16 isn't needed. It's pretty nice except for an area of flaky paint, but it's only got 4K on it. No scrapes, dings and runs true.
