Help ID my 80s Japanese Bianchi 12-speed?

The bike

I bought this bike yesterday for $200. I liked the color (yeah not celeste but w/e), it rides well, and it was in decent shape.

There isn't any decal denoting the model, but here's what I know:
  • It's made in Japan
  • It has a dual chainring and 6 gears
  • Downtube shifters
  • Chromoly frame
  • Most components are Suntour
  • There's a Piaggio sticker on the tube

Anyone know which model this is? Thanks!

@Bianchigirll might know. What you've got looks pretty decent, whatever it is... DT shifters, mostly aluminum components...

I would say that it's a mid-late 70's 100% Japanese bike made under contract for Bianchi. In the early 70's Japanese cycle makers were trying very hard to shed their crap reputation by offering components that were better designed, finished and priced at half to 2/3ds of what European makers were offering. Your Bianchi has SunTour Cyclones, one of the best mechs available at the time. The shift-levers are also suntours and very good. Sake-Ringyo, SR, made the seatpost, a Campag NR copy, the bars & stem, both Cinelli copies. The cranks are also SR, but a budget model. I'm guessing that the brakes are Dia-Compe "G"

The frame is similarly trying to make the Japanese flag fly high. Half chrome stays & forks, cromo tubing, forged, non adjustable dropouts are all features that you find on nice frames. The budget nature of the frame shows in it's pre-plating metal polishing at the rear dropouts.

You bought a mid-range Bianchi in a very nice colour for $200 bones. Very nice.

The Bianchi experts should be along soon!
