There is no serial number on my motobecane..

I've been curious to find out exactly what year my grand record is but the other day I spent some time looking up serial number deciphering for old motobecanes (found a bunch of speculation) and when I went to see what my serial number even was I realized there is no serial number stamped anywhere on the bike! Original paint and everything.. but no number. Does anyone more familiar with motos have any idea why?

I cannot particularly vouch for a Moto, but a lot of European bikes came through with no serial numbers stamped anywhere on them. No idea why. Perhaps during the bike boom years, they were cranking them out so fast that that particular part of the manufacturing process was skipped. Have you checked in every spot on the frame ? Sometimes the serial number is stamped on the back of the seat tube, or near the seat post.

My Team Champion shares its serial with another Team Champion. Go figure.

There's no serial number on my Klein, there's no serial number on my unknown frame badged as a Rossin. There's no serial number on my Basso, and of the 5 Guerciottis I've run across, none had anything but the frame size stamped on it.

Unusual? No. If your local PD hasn't brought their hammer and punch set out to engrave a serial number to your top tube yet, stop worrying.

One oddball place is on the fork in the section inside the head tube...trying to recall where I saw that but I did once.

I have a couple of Motos without S/N's, and those that do don't seem to tell me anything. TMar says (and if he says it, you can believe it!) that your best bet is to check for date codes on those components that are most likely to be original to the bike. If your GR is still possessed of its headbadge and paint scheme, it's often pretty easy to figure out.

Pictures, please!

I've got a 1975 le Champion and looked for a SN last night. The only thing I could find was a number stamped into the lower Campy dropout on the non-drive side. Did Campy use serial numbers or could that be for the bike?
