OK, but this is the 1984 Motobecane catalogue. What do you mean by "confirmed by MBK"? 1984 is the final year of bikes carrying the Motobecane name and colors. The La Redoute team, and thus the team replica bike, existed for only one more year, carrying the MBK name and colors. I've seen no marketing materials from MBK listing this bike, though clearly some were produced (or updated) for that racing season. At the same time, we have several years of Motobecane ads, catalogs, and dealer communiqués establishing an "a la carte" program and a top "SP" or "Special Pro" model that was fully customizable--for the French market, anyway. The resulting bikes could be exact team replicas or end up different, according to customer preferences and availability of supplies and parts. The La Redoute Replica describes one set of options, and the only top-of-the-line configuration, or Team Champion, exported to my country. Eventually, production of this model variant stopped--when? When the parts ran out? When the La Redoute team was canceled? Did MBK even sell the bike to the public? I've also seen no indication that MBK continued the "a la carte" program. I suspect that under Motobecane management the program was already winding down--that would be 1984. By the way, you can distinguish between a 1983 and 1984 team replica/Team Champion by the headset: The A9 roller bearing model was not made available to the public until 1984. Another clue is the pedals. Extremely late models like the MBK team bike in the auction, or my SP, came with Maillard 700 CXC platform, or "aero" pedals. The '84 catalogue doesn't show this; it was printed too early. I would be interested if anyone has actually seen a team replica in Motobecane colors with this headset and these pedals. They are truly end of the line Motobecanes, and like the MBK LR team bike, perhaps not offered to the public.
