jar351, I have the sister to your Legend. A 1983 56cm model, serial number EY04293. Oddly enough, my 58 cm 1983 Legend Compe has serial number EY04307. That makes the three bikes fall within 47 numbers of each other. Interesting.
That's either a heck of a coincidence, or (as I suspect), they didn't make many of the 1983 versons of the Legend. From my observations, it seems the similar 1984 model is much more common.
I was lucky to find my Legend in mostly original condition. Except for the saddle, one tube, and missing gum hoods, it still has all the original parts including the tires, bar tape (?), water bottle and cage.
We've collected some serial numbers from 1983 Lotus bikes and they share the "EY" prefix. Does anyone see how that could be a logical code for '83, or is it proprietary? We have over 100 Lotus serial numbers on the site and still can't figure out the sequence. T-Mar, do you have any ideas?
