With A handle like toecutter have I got the bike for U.
1975 Z1 900B , rassk rear sets, solid state ing. 29 MM smoothbores ect...... and yes It is A Z1B.
Ah yes, takes me back...
Two friends of mine, both brothers, had one of those at some point. The eldest had a very clean one, with a 1015 kit in it, along with the requisite un-baffled Kirker. That thing was fierce! One morning, I arrived for our daily bike pool to work, and noticed it wasn't out front, which was common, as he usually parked inside. When he opened the door and I saw it wasn't in his apartment..."Dude, where's your bike?" Needless to say, it was a very bad day for him. Never saw it again.
His younger brother sold his (74 Z1) a few months ago, lacking the motivation to restore it. Hopefully, it will be brought back to its original glory by the new owner.
