I have now looked at a couple of Z900 and one thing that differs between the two that have been presented to me is that one has a single disc up front and the other has twin disks.
Is the change to two discs a factory change or an owner upgrade?
Also, and I may be about to be banned permanently form this forum for blasphamy but what are the major differences between a Z1 and a Z900 as 'Mad Frank' is advertising one bike but calling it the same thing.....

Sorry for the daft questions but I am new to classic bike buying...LOL
