Motobecane Serial Number Decoder
I've checked out those exact sites back in 2009 when I originally posted my photos of the Super Mirage. Comparing the catalog photos and spec sheets, I determined it is a '77. Well, there you go, then. Seems like you already know the answer. It can sometimes be difficult to nail down exact year of manufacture on these things as they rolled over both old photos and specs in some catalogs, and components may have fluctuated a bit from catalog specs depending on availability.
