If you compare the published geometry for both bikes, the Expedition has slightly different geometry than the Miyata 1000. Finally, Jim confirmed the frame was made by Miyata in Japan for Specialized. Put together, multiple sources of information all point to the same things: not a clone but built by Miyata.
So what are the differences between a like sized Expedition and Miyata 1000? From all I could find on the Expedition, which wasn't much, it seems it may have a 1.5 to 2 degree steeper seat tube in the common 54 & 56cm sizes - although it appears Specialized measured frame size CTC whereas Miyata did CTT, so a direct comparison may not be possible. Nevertheless, I'd love to find a 54cm Expedition to try to determine what the "special sauce" might be.
