Miyata 912 age?
I'm picking this up locally tomorrow and am wondering what year it is. I was assuming the black and pink color scheme
was just made one year but I believe thats not true. Other than needing new tires it is in very nice shape. Any idea what year it might be?
I believe everything is original on it even the seat.

Look like an 86:
See 86 catalogue here, page 7.

Nailed it. I used to own one. Very nice bike. That one looks pretty much bone stock. Just need some hoods, a good once-over, and maybe some more generously sized fresh rubber (it'll fit 28s, easy).

Be careful saying "it'll fit 28s easy" -- I have a '86 Miyata 710 that has < maybe > 1mm clearance between the top of the tire and the bottom of the fork crown with my Vittoria Rubino Pro 28s --So close that if the tire is not seated absolutely evenly all the way around the rim, it'll touch. I'll probably go with a 25 on the front next time it needs tires. 28 is ok on the rear.

That said, obviously need to consider all the usual caveats about nominal tire sizing (I wouldn't be confident of a 28mm GP4000 fitting, say, as I've measured those supple, stretchy, capacious tires at fully 32mm seated on a set of rims recently), specific choice of brake caliper, etc.
YMMV.

Ryan had a 79 Miyata 912 that was a great ride with gorgeous Shimano 600 Arabesque components.
Ryan sold it,
Ryan regrets it,
Don't be like Ryan.
Nice Score OP Enjoy

I had that same bike, same year, same size. Top tube was too long for me. The 60cm 710 has a 3cm shorter top tube than the 60cm 912. Thats an aggressive responsive bike! I miss it, but no rug rats. It fidnt dit.

Here's a pic showing the 28mm tire/fork clearance on my '86 Miyata 710. These were brand new Vittoria Rubino Pro 28mm tires when this pic was taken.
One of the changes for the 710 in '86 was a new CrMo fork for 700c tires. I'd imagine the 912 used the same fork in '86 - the catalog simply says CrMo tubing, semi-sloping cast crown, forged TF ends for both...

Seeing these tire clearance shots of mid 80’s 912’s and 710’s reminds me why my ‘79 912, which came with 27” wheels and long ago converted to 700x28’s with fenders, continues to please. It accepts true 32’s without the fenders. This shot was after the Gugificazione addition of the brazed on centerpull front brake (to accommodate that front rack and rando bag) but before reinstallation of fenders. And the top tube on my 25”/62.5cm is comfortably (for me) short at 58cm, too.

I had a 90 912 and absolutely loved that bike. It was a tiny bit big for me, so I sold it. 
My 90 would only fit 700x26c. What was the last year that the 912 came with 27 wheels? Are those comparable, ride and handling/geometry, to 912 of later years? I would Love to have basically the same bike that I could fit 700c wheels and larger tires on.

Looks like theyd already switched the 912 to 700C by 1981, according to the catalog for that year.
