Sean, this is definitely a 1985 model, as the serial number indicates February 1985. That explains the missing Piaggio decal. The brakes are Shimano Z-series. It's now clear that the fork is chromed, so it is Canadian market. Tubing and components, except for the previously mentioned rear derailleur and seat post, are the same as for the 1984 Bianchi Bici II. So, you've got yourself a 1985 Bianchi Bici II. Enjoy!
