OK people, I've only got another 500 posts remaining , so I've decided to make an attempt at decrypting one last serial number format. It seems Motobecane's format has been giving people fits, so I'm willing to give it a shot, if you want to play along.
Most of you already know the drill. Post pictures of your Motobecane (full drive side and detail pictures of major components, tubing decal, headbadge and serial numbers). Provide as much info as possible on the components including brand, model and date codes (when available). Refer to the components page of the Vintage-Trek website if you need a primer on component date codes. Bonus points if you already know the year.
NOTE: Motobecane often have several sets of numbers on the bottom bracket shell. I need ALL of them, as we don't which which holds the key to dating.
I'll be tabulating and analyzing the data. A summary of the findings will be posted here (i.e. post #1). Hopefully, it will as successful as the other, similar threads (Bianchi, Centurion, Fuji, Miyata, Nishiki, etc.). TIA.
