A couple observations about the later Miyata 1000LT that Golden Boy has, and my 1000LT from 1989. Perhaps by that at date Miyata wasn’t really trying to compete with the real purpose built heavy duty tourers. I think I saw that the LT was for “light tourer”.
Comparing 1988 to the later LT from 1989, the fork offset decreased from 65 to 60mm. Specs list a tall 11” bb height too. My 89 measures 11 1/4” with 35 Paselas. I’m not saying it’s sporty, but without a bunch of accessories on it, I was a bit surprised that the ride wasn’t boatish as I was expecting. Was Miyata aiming for a wider audience?
