Mine is in storage over in Vancouver. I've not seen it for 16 years. From memory: mine is an '82 or '83. The drive train was all SunTour. I think that someone has changed out your headset and brakes. Someone has juiced this one up. You are going to love it. IMHO, it is an excellent middle between nervous handling racers and lazy tourers — a true clubman in the old tradition. Miyata's tubing and their frame assembly is very respected by those who are not interested in collecting bling points. I wish mine was here in Japan.

If you look on the web, you'll find that a kind enthusiast has put up Miyata catalogues for several years in pdf. You can download them.
