I was in the bike business starting in 1974 and sold Kabuki (and CITOH) bikes in the mid-1970's through 1978. The OP's version is probably a late 70's version, dated primarily because it's a 12speed bike rather than a 10 speed. The Japanese manufacturers were just beginning to introduce 12 speed versions of their bikes in around 1978. The bike is a basic, entry level bike, but like all the Japanese bikes of that era, was quite good for its intended market. The die-cast frames were heavy, but very durable. The rims, handlebars, etc. were probably steel so all-in-all, the bikes were heavy. The seat post with its expander plug was heavy as well. I think it was around 1978 when Bridgestone (maker of Kabuki labeled bikes) introduced a more conventional, lugged cro-moly frame touring bike - also a great bike for its intended market. From that point forward, they made better and better bikes - lighter bikes - better components, etc. Until they left the US market in 1994 (I was still selling them), I think they made one of the most consistent, broad product lines available.
