Kabuki was Bridgestone before their 2nd try at the US market in the mid-eighties. Bridgestones from the mid to late 80's have a bit of a cult status due to the influence of one Grant Peterson who had, and still maintains, his own ideas of how a bike should look, handle, be constructed, and so forth. Our bikes predate that revolution, and do not garner the same respect. However, I will say that I have a similar price-point Lotus from the same year and the frame on the Kabuki has a much better build quality. In fact, I was rather suprized as some of the sloppiness of the lugs on the Lotus as they were generally much better than this one. Not enough of a population to draw any scientific conclusions, but good enoguh for network news.
Enjoy it. It looks like a nice bike regardless of the name on the headbadge.
