Help me date / model this centurion.
 
Trying to date a centurion.
M6C06306

everything I look for says there should be a Y following the M but there’s not. It begins with M6.

Long lugs
SR seatpost is a campy knock off. All parts interchangeable.
SR stem is nicely milled, makes me think racing not touring
original owners manual

funny, dad warmed up his pen on the cover, but never filled out the reg card.

Looks like a 1977-ish Semi Pro that has had some paint stripped.

Immediately pegged as a Semi Pro, 77-79. But I have no firm proof.

Link to Asian Serial Number Guide

MIKI (Japan): MyFxxxx; BF member Hummer believes 3rd character is a month indicator using A to M, with I omitted.
y indicates a numeric character designating the last digit of the year (i.e. 1 = 1971 or 1981, 2 = 1972 or 1982, etc.). With such codes, you have to determine the decade based on frame characteristics, components, etc.

So frame was serialized in March 1976

jPrichard10 12-10-25 03:17 PM

I shouldn't ask, but what size is this?

Dad liked 58–60

That's a sweet-lookin' sled. I bet it rides as nice as it looks. And that SR stem is the business... one of the prettiest ever, I think.

The bar tape and hoods aren't doin' it for me, though.

No one does.

The style of headbadge would seem to confirm a bike made between 76-79.

jPrichard10 12-11-25 09:49 AM

Just noticed the FD has been replaced, and the rims (or more likely the wheels).

But everything else on there is mighty fine

sd5782 12-11-25 11:54 AM

That is just so very tasteful.

Robvolz 12-11-25 12:53 PM

I will move to the for sale section shortly.

maybe after I replace the tape.

cb400bill 12-11-25 01:50 PM

I once owned a pearl yellow 79 Semi Pro. Great riding bikes.

Robvolz 12-11-25 02:42 PM

It measures 60cm center to top
