Koga Miyata from the 80s?

Shimano brakes, new tyres and info about the frame


The bike
So I've picked up this Koga Miyata just a few weeks ago. But because I'm silly I didn't realise it was too big for me. So I'm thinking of selling it on. Do any of you have some idea what it might be worth? And an estimate of when it was made? I presume mid 80s. I paid 350€ and honestly it's in the ballpark of what you can expect for a vintage bike in good condition with a good drivetrain.
I changed the stem, the handlebars, the tape, rim tape, tubes and tyres. Cleaned and oiled the chain. Is 450€ too much to ask? It's a bit less than what I paid + upgrades and I hardly rode 100km (62miles) on it.
It has Shimano z series with indexed gears 6x2.
Thank you!

Nice build, is the frame to tall for? It is a long reach you have set for the cockpit, that can be awkward. Your bike is 1986 by my guess.
I am not familiar with the FM2 and HM2 tubeset, is that the through tube with the rubber grommets? The frames with the grommets were good but the cut-outs for the cable created a stress riser and could or would crack. Inspect those spots well. From the parts it appears mid-level.
I do not think it's to bad to ask €450, but that price may be optimistic, just make sure that you hi light the positive, and that the size not right as the only reason to sell. That bike has many positives. It sounds like you know your market well.

Looks smaller than the Peugeot the op was interested in.
150€ for a vintage Peugeot?
Unless the tires have a directional tread, ensure the tire labels can be read from the drive side and they're centered over the valve stems.
And try to avoid non drive-side pics until you've taken plenty of them from the drive-side.

Yeah I don't know about the Peugeot, in the end I didn't see it in person, but it was advertised as a 54cm frame

I would say put the original stem and bars back on the bike if you have them and ask 400 to start and be willing to accept less. On bikes like this you seldom get extra for upgrades so you should keep them and it would likely sell as good or better with the original stuff. The nice clean setup and that it is ready to ride with good brake pads cables new bar tape tires should get a nice premium.

On a straight top tube frame learn how to eyeball the frame size by looking at the steerer tube.

You want a bike where this bit here is shorter.
Also you can start with a $350 dollar bike, slap $350 worth of "upgrades", and still have a $350 dollar bike. If you want the money from the upgrades back you would need to sell the upgrades.

By "straight" top tube you mean "level" or "horizontal," I imagine. That said, your sizing advice applies to (straight) sloping top tubes, too.

The logic of the price doesn't fully make sense to me. Is it worth nothing that the bike has new tyres, tubes, rim tapes etc...? What if I had put a new wheelset?

For wheelsets it is nice to have a high end pair to enjoy. You basically keep the original ones in the closet so if you sell the bike you can put those back in.
