I have owned this bike 23 years. The numbers indicate it is a Z1b with a Z1a motor . I am offering for sale as unregistered, this is a genuine reluctant sale. I decided to sell the bike a few years ago due to health reasons but did not want to offer it for sale without making sure it would be good for another 20 years or more hopefully and have tried to ensure this to the best of my ability. I have kept as genuine as possible, but have had to use aftermarket parts and have been fussy that their appearance and quality be assured as much as practical.
