Obtained this frame/fork recently along with 3 boxes of bike “stuff.” Seller said some of the parts for the frame might be in the boxes. Seller also included Ukai 700 wheel set that he said were original to the bike

The only other parts that I found I thought might be original were the 600 Arabesque drs and shifters.

Only other possible identifiers are: Tange stamped in fork drops/Shimano stamped into rear drops.

Decal on this frame says Super. Not Super Pista or Super Junk, just Super. It feels light, not like hi-ten but more like cro-mo.

My research turned up very little info. I couldn’t even find a reference to or photos of the frame except that Piaggio purchased the name and had bikes manufactured in Japan for about 1981 to 1985.

What do I have here, middle of the road model or bottom feeder? My guess is an early to mid 80’s Japanese built bike.

I was looking for a cheap rider buildup from my parts stash but there is a headset issue has me wondering. When I placed the fork in the head tube it seemed way too long. (I found traces of the same color paint on the fork tube so I believe it is original) but it doesn’t seem that “normal sized” races and bearings will pick up that much “slack.”

Before I saw the extra from the fork tube if it has sufficient threads to fit properly, I don’t want to ruin something that may be of value. Head cups and odd piece show in case they might be applicable

One final request, I was unable to find a diagram showing the exact parts for the shifters shown. Any help anyone?

Would appreciate any info you can provide.
