The 1200 appeared twice in Miyata's line-up, first in 1982 and then after a long absence it re-appeared in 1988, for a single year. You have the latter. It was positioned just above the 912 and below the Team Miyata. It is very close to Team frame, but not quite the same. While it is full CrMo and uses the excellent Spline Triple Butted main tubes and spline fork blades, it lacks the spline chainstays, investment cast head lugs and Shimano forged dropouts of the Team. The bottom bracket is also slightly lower, but otherwise the geometry matches the Team. Still very good, but I guess they had to downgrade ithe frame somehow from the Team. The Sante group is excellent though not quite up to the standards of Dura-Ace in the long run.

I've never ridden a 1200 but the Team of the era was excellent and earlier Pro was also very good, so there's no reason to believe this isn't a very fine competition model also. The Pro had disappeared from Miyata's lineup the previous year, so I like to think of the 1200 as the black-tie version of the Pro. The Pro was performance oriented and the appearance, while good, was functional in the traditional sense. The 1200 added high fashion, though the look did not appeal to everyone. It's pretty close to the cycling equivalent of James Bond in a tux.
