Frames of that era seemed to have an I.D. system that is starting to make sense - we are confident we can date these frames. Your frame has a 'different' I.D. number and its location is different. The Piaggio era frames had the serial number and date stamped on the seat cluster. I know other readers of this forum may be able to make sense of your bike's serial number.

Your frame has a 'correct looking' Made in Italy decal in a position I would expect to see this decal. Do you feel the frame is in its original condition?

I believe the 2 sets of biddon mounts (down tube and seat tube) and pump peg on head tube were mid to late 80's improvements in frame design.

By 1990 and with Moser leading the way using Shimano, I wouldn't be surprised to see Shimano on an Italian frame. That being said, you cannot confirm the original components anyway.

Best of luck in your quest - I can understand your 'need to know'.
